Module codec 

Standard (RFC 4648) Base64 encode/decode with no external dependencies.

Used for two purposes:

• Encoding an embedded C2PA Manifest Store into a data:application/c2pa;base64, reference and decoding it back out again ([crate::extract]).
• Encoding the hard-binding hash value when serialising a c2pa.hash.data assertion to JSON (crate::hardbinding).
