Refactor Nyx in Python #311
Description
High level description
The first part of this work will include creating, refactoring, and re-enabling the Python interface in Nyx, which was removed in #305 for the sake of time.
Nyx is currently one (giant) library. I've learned on ANISE that it's very useful to separate out the code in a workspace. Nyx-Insight may eventually be an additional package to Nyx in the future.
Requirements
Basically, make it a pleasure to use, just like it's a pleasure to use ANISE in Python and in Rust.
Test plans
Reenable all of the test plans currently in the code, but disabled in CI.
