Encode a base256 ByteString as base16.

Uses ARM NEON extensions when available, otherwise a pure Haskell scalar loop.

>>> encode "hello world"
"68656c6c6f20776f726c64"

Decode a base16 ByteString to base256.

Uses ARM NEON extensions when available, otherwise a pure Haskell scalar loop. Invalid inputs (including odd-length inputs) will produce Nothing.

>>> decode "68656c6c6f20776f726c64"
Just "hello world"
>>> decode "068656c6c6f20776f726c64" -- odd-length
Nothing
