An abstraction over something which can serialize to/from bytes.

[JakeWharton]

I would expect the JSON, ProtoBuf, and CBOR classes to all implement some common type to facilitate serialization to/from a T+KSerializer<T> to bytes. This is needed for something like a Retrofit 2 converter.

Currently you can work around it with extension methods and passing around a pair of method references (but that's super annoying).

For now I'm using method references to accomplish this (example 1, example 2) which works, but being able to accept the JSON or ProtoBuf instance directly would greatly improve the converter API.
