Allow different serialization mechanisms via plug-ins

[mgibowski]

It is not guaranteed that serialization with :erlang.term_to_binary and desarialization with :erlang.binary_to_term works correctly when using different OTP versions, see ERL-431 for an example.

I suggest addressing this issue by introducing a Serializer behavior and the default implementation being the current one and shipping with the library. There should be an option for users to provide an alternative implementation of the Serializer. I don't have much knowledge on this topic, but a quick internet search suggests me msgpax or some BSON implementation could be good candidates.
