Encode a ByteString value in base16 (i.e. hexadecimal). Encoded values will always have a length that is a multiple of 2.
Examples:
encode "foo" == "666f6f"Modulebase16-bytestring-1.0.2.0Haskell2010

Decode a base16-encoded ByteString value.
If errors are encountered during the decoding process,
then an error message and character offset will be returned in
the Left clause of the coproduct.
Examples:
decode "666f6f" == Right "foo"
decode "66quux" == Left "invalid character at offset: 2"
decode "666quux" == Left "invalid character at offset: 3"Decode a Base16-encoded ByteString value leniently, using a strategy that never fails.
N.B.: this is not RFC 4648-compliant
Examples:
decodeLenient "666f6f" == "foo"
decodeLenient "66quuxx" == "f"
decodeLenient "666quux" == "f"
decodeLenient "666fquu" -- "fo"
