This contract extends the ERC20Upgradeable contract and adds the ability to burn tokens. It allows the caller to destroy a specified amount of tokens from their own balance or from another account's balance, deducting from the caller's allowance if necessary.

/**
 * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
 * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an
 * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
 * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
 *
 * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be
 * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in
 * case an upgrade adds a module that needs to be initialized.
 *
 * For example:
 *
 * [.hljs-theme-light.nopadding]
 * ```solidity
 * contract MyToken is ERC20Upgradeable {
 *     function initialize() initializer public {
 *         __ERC20_init("MyToken", "MTK");
 *     }
 * }
 *
 * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {
 *     function initializeV2() reinitializer(2) public {
 *         __ERC20Permit_init("MyToken");
 *     }
 * }
 * ```
 *
 * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
 * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
 *
 * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
 * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
 *
 * [CAUTION]
 * ====
 * Avoid leaving a contract uninitialized.
 *
 * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
 * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke
 * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:
 *
 * [.hljs-theme-light.nopadding]
 * ```
 * /// @custom:oz-upgrades-unsafe-allow constructor
 * constructor() {

 * that only accounts with this role will be able to grant or revoke other
 * roles. More complex role relationships can be created by using
 * {_setRoleAdmin}.
 *
 * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to

     * * For any other selector, if the restricted function is set on an upgradeable contract, an upgrade may remove

 * @dev A vesting wallet is an ownable contract that can receive native currency and ERC20 tokens, and release these
 * assets to the wallet owner, also referred to as "beneficiary", according to a vesting schedule.
 *
 * Any assets transferred to this contract will follow the vesting schedule as if they were locked from the beginning.
 * Consequently, if the vesting has already started, any amount of tokens sent to this contract will (at least partly)
 * be immediately releasable.
 *
 * By setting the duration to 0, one can configure this contract to behave like an asset timelock that hold tokens for
 * a beneficiary until a specified time.
 *
 * NOTE: Since the wallet is {Ownable}, and ownership can be transferred, it is possible to sell unvested tokens.
 * Preventing this in a smart contract is difficult, considering that: 1) a beneficiary address could be a
 * counterfactually deployed contract, 2) there is likely to be a migration path for EOAs to become contracts in the
 * near future.
 *
 * NOTE: When using this contract with any token whose balance is adjusted automatically (i.e. a rebase token), make
 * sure to account the supply/balance adjustment in the vesting schedule to ensure the vested amount is as intended.

/**
 * @dev This module connects a {Governor} instance to an {AccessManager} instance, allowing the governor to make calls
 * that are delay-restricted by the manager using the normal {queue} workflow. An optional base delay is applied to
 * operations that are not delayed externally by the manager. Execution of a proposal will be delayed as much as
 * necessary to meet the required delays of all of its operations.
 *
 * This extension allows the governor to hold and use its own assets and permissions, unlike {GovernorTimelockControl}
 * and {GovernorTimelockCompound}, where the timelock is a separate contract that must be the one to hold assets and
 * permissions. Operations that are delay-restricted by the manager, however, will be executed through the
 * {AccessManager-execute} function.
 *
 * ==== Security Considerations
 *
 * Some operations may be cancelable in the `AccessManager` by the admin or a set of guardians, depending on the
 * restricted function being invoked. Since proposals are atomic, the cancellation by a guardian of a single operation
 * in a proposal will cause all of the proposal to become unable to execute. Consider proposing cancellable operations
 * separately.
 *
 * By default, function calls will be routed through the associated `AccessManager` whenever it claims the target
 * function to be restricted by it. However, admins may configure the manager to make that claim for functions that a
 * governor would want to call directly (e.g., token transfers) in an attempt to deny it access to those functions. To
 * mitigate this attack vector, the governor is able to ignore the restrictions claimed by the `AccessManager` using
 * {setAccessManagerIgnored}. While permanent denial of service is mitigated, temporary DoS may still be technically
 * possible. All of the governor's own functions (e.g., {setBaseDelaySeconds}) ignore the `AccessManager` by default.

/**
 * @dev Extension of {Governor} that binds the execution process to an instance of {TimelockController}. This adds a
 * delay, enforced by the {TimelockController} to all successful proposal (in addition to the voting duration). The
 * {Governor} needs the proposer (and ideally the executor) roles for the {Governor} to work properly.
 *
 * Using this model means the proposal will be operated by the {TimelockController} and not by the {Governor}. Thus,
 * the assets and permissions must be attached to the {TimelockController}. Any asset sent to the {Governor} will be
 * inaccessible from a proposal, unless executed via {Governor-relay}.
 *
 * WARNING: Setting up the TimelockController to have additional proposers or cancellers besides the governor is very
 * risky, as it grants them the ability to: 1) execute operations as the timelock, and thus possibly performing
 * operations or accessing funds that are expected to only be accessible through a vote, and 2) block governance
 * proposals that have been approved by the voters, effectively executing a Denial of Service attack.
 *
 * NOTE: `AccessManager` does not support scheduling more than one operation with the same target and calldata at
 * the same time. See {AccessManager-schedule} for a workaround.

 * "representative" that will pool delegated voting units from different accounts and can then use it to vote in
 * decisions. In fact, voting units _must_ be delegated in order to count as actual votes, and an account has to
 * delegate those votes to itself if it wishes to participate in decisions and does not have a trusted representative.
 *
 * This contract is often combined with a token contract such that voting units correspond to token units. For an
 * example, see {ERC721Votes}.
 *
 * The full history of delegate votes is tracked on-chain so that governance protocols can consider votes as distributed
 * at a particular block number to protect against flash loans and double voting. The opt-in delegate system makes the
 * cost of this history tracking optional.
 *
 * When using this module the derived contract must implement {_getVotingUnits} (for example, make it return
 * {ERC721-balanceOf}), and can use {_transferVotingUnits} to track a change in the distribution of those units (in the
 * previous example, it would be included in {ERC721-_beforeTokenTransfer}).

/**
 * @dev A forwarder compatible with ERC2771 contracts. See {ERC2771Context}.
 *
 * This forwarder operates on forward requests that include:
 *
 * * `from`: An address to operate on behalf of. It is required to be equal to the request signer.
 * * `to`: The address that should be called.
 * * `value`: The amount of native token to attach with the requested call.
 * * `gas`: The amount of gas limit that will be forwarded with the requested call.
 * * `nonce`: A unique transaction ordering identifier to avoid replayability and request invalidation.
 * * `deadline`: A timestamp after which the request is not executable anymore.
 * * `data`: Encoded `msg.data` to send with the requested call.
 *
 * Relayers are able to submit batches if they are processing a high volume of requests. With high
 * throughput, relayers may run into limitations of the chain such as limits on the number of
 * transactions in the mempool. In these cases the recommendation is to distribute the load among
 * multiple accounts.
 *
 * NOTE: Batching requests includes an optional refund for unused `msg.value` that is achieved by
 * performing a call with empty calldata. While this is within the bounds of ERC-2771 compliance,
 * if the refund receiver happens to consider the forwarder a trusted forwarder, it MUST properly
 * handle `msg.data.length == 0`. `ERC2771Context` in OpenZeppelin Contracts versions prior to 4.9.3
 * do not handle this properly.
 *
 * ==== Security Considerations
 *
 * If a relayer submits a forward request, it should be willing to pay up to 100% of the gas amount
 * specified in the request. This contract does not implement any kind of retribution for this gas,
 * and it is assumed that there is an out of band incentive for relayers to pay for execution on
 * behalf of signers. Often, the relayer is operated by a project that will consider it a user
 * acquisition cost.
 *
 * By offering to pay for gas, relayers are at risk of having that gas used by an attacker toward
 * some other purpose that is not aligned with the expected out of band incentives. If you operate a
 * relayer, consider whitelisting target contracts and function selectors. When relaying ERC-721 or
 * ERC-1155 transfers specifically, consider rejecting the use of the `data` field, since it can be
 * used to execute arbitrary code.

 * contract and not the "assets" token which is an independent contract.
 *
 * [CAUTION]
 * ====
 * In empty (or nearly empty) ERC-4626 vaults, deposits are at high risk of being stolen through frontrunning
 * with a "donation" to the vault that inflates the price of a share. This is variously known as a donation or inflation
 * attack and is essentially a problem of slippage. Vault deployers can protect against this attack by making an initial
 * deposit of a non-trivial amount of the asset, such that price manipulation becomes infeasible. Withdrawals may
 * similarly be affected by slippage. Users can protect against this attack as well as unexpected slippage in general by
 * verifying the amount received is as expected, using a wrapper that performs these checks such as
 * https://github.com/fei-protocol/ERC4626#erc4626router-and-base[ERC4626Router].
 *
 * Since v4.9, this implementation uses virtual assets and shares to mitigate that risk. The `_decimalsOffset()`
 * corresponds to an offset in the decimal representation between the underlying asset's decimals and the vault
 * decimals. This offset also determines the rate of virtual shares to virtual assets in the vault, which itself
 * determines the initial exchange rate. While not fully preventing the attack, analysis shows that the default offset
 * (0) makes it non-profitable, as a result of the value being captured by the virtual shares (out of the attacker's
 * donation) matching the attacker's expected gains. With a larger offset, the attack becomes orders of magnitude more
 * expensive than it is profitable. More details about the underlying math can be found
 * xref:erc4626.adoc#inflation-attack[here].
 *
 * The drawback of this approach is that the virtual shares do capture (a very small) part of the value being accrued
 * to the vault. Also, if the vault experiences losses, the users try to exit the vault, the virtual shares and assets
 * will cause the first user to exit to experience reduced losses in detriment to the last users that will experience
 * bigger losses. Developers willing to revert back to the pre-v4.9 behavior just need to override the
 * `_convertToShares` and `_convertToAssets` functions.
 *

/**
 * @dev Interface of the ERC20 Permit extension allowing approvals to be made via signatures, as defined in
 * https://eips.ethereum.org/EIPS/eip-2612[EIP-2612].
 *
 * Adds the {permit} method, which can be used to change an account's ERC20 allowance (see {IERC20-allowance}) by
 * presenting a message signed by the account. By not relying on {IERC20-approve}, the token holder account doesn't
 * need to send a transaction, and thus is not required to hold Ether at all.
 *
 * ==== Security Considerations
 *
 * There are two important considerations concerning the use of `permit`. The first is that a valid permit signature
 * expresses an allowance, and it should not be assumed to convey additional meaning. In particular, it should not be
 * considered as an intention to spend the allowance in any specific way. The second is that because permits have
 * built-in replay protection and can be submitted by anyone, they can be frontrun. A protocol that uses permits should
 * take this into consideration and allow a `permit` call to fail. Combining these two aspects, a pattern that may be
 * generally recommended is:
 *
 * ```solidity
 * function doThingWithPermit(..., uint256 value, uint256 deadline, uint8 v, bytes32 r, bytes32 s) public {
 *     try token.permit(msg.sender, address(this), value, deadline, v, r, s) {} catch {}
 *     doThing(..., value);
 * }
 *
 * function doThing(..., uint256 value) public {
 *     token.safeTransferFrom(msg.sender, address(this), value);
 *     ...
 * }
 * ```
 *
 * Observe that: 1) `msg.sender` is used as the owner, leaving no ambiguity as to the signer intent, and 2) the use of
 * `try/catch` allows the permit to fail and makes the code tolerant to frontrunning. (See also
 * {SafeERC20-safeTransferFrom}).
 *
 * Additionally, note that smart contract wallets (such as Argent or Safe) are not able to produce permit signatures, so
 * contracts should have entry points that don't rely on permit.
