ValarDragon 12892e8c23 blake2b,blake2s: implement BinaryMarshaler, BinaryUnmarshaler 
The marshal method allows the hash's internal state to be serialized and
unmarshaled at a later time, without having the re-write the entire stream
of data that was already written to the hash.

Fixes golang/go#24548
