Hashlips On Chain Metadata Library

This function encodes a given byte array into a base64 string. It does this by looping through the byte array, breaking each 3 bytes into 4 6-bit chunks, and then using a lookup table to convert each 6-bit chunk into a base64 character. The lookup table is stored as a string, and the encoded string is stored in a new string with 32 bytes of padding. Finally, the function adds padding characters to the end of the encoded string if necessary. (autogenerated documentation)
