What is the go-to way for serializing a tag value to JSON?

`com.inductiveautomation.perspective.gateway.messages.json.QualifiedValueSerializer` exists, but it is kinda lame.

It seems to fail on anything except primitive values, and I'd like to be able to serialize `Document`, `Dataset`, and `Array` data types.

There's a TagGson utility class with helpers to create a Gson instance capable of serializing almost anything in the tag system.
