Pass serializer into aggregate serialization interface methods #56
Description
Problem
The proposal in #55 got me thinking.
In Getty JSON, the implementation for the aggregate serialization interfaces (e.g., getty.ser.Seq, getty.ser.Map) has a field referencing the serializer passed to serializeSeq, serializeStruct, etc. I believe the field is used in every single one of the aggregate interface methods (no surprise there; most of them are literally called serializeX).
But having to carry this field around in the implementation isn't ideal. Any SB that calls serializeSeq already has a reference to the same serializer, so there's no need to store it in the implementation. Also, it makes more sense to have the serializer as a parameter of the methods doing the serialization than on the impl itself.
Proposal
So, what if we pass in the serializer to the methods like serializeElement, serializeKey, and so on? The SB calling serializeStruct would always have a reference to the relevant serializer so it'd be easy to pass it in for them.
This would simplify implementations of the aggregate interfaces since they'd no longer need to keep a redundant serializer around.
