Analysis tests

[jwest115]

Addresses the analysis test portion of nasa/fprime#4162.

Python script for converting the fprime-python-model analysis data structure to JSON. Improvements/work to go so that the diff between fprime-python-model and fpp-to-json is 1-1 are:

• Fix class names JSON (in some contexts, the fpp-to-json does not include class names). Examples to look at would be the typeMap vs. struct and anon struct types.
• Consider Optionals - right now I do not wrap optionals in a “Some" dictionary
• Fix Enum encoding
• JSON encoding for topologies, component instances, etc. I was mainly focused on symbol maps, type maps, component maps, and value maps. I am sure there will be other “special cases” to account for once encoding topologies, component instances, and the state machine analysis.
• Test script for running the JSON converter against all test cases and diffing them against their reference fpp-to-json analysis output.

Note: While writing these tests, I realized there was something translated incorrectly in the analysis location specifier map translation (the fix is included in this PR).
