This PR is diverting from it's original goal, and it has accomplished several tangential things along the way.

• obfs4 forward proxy working!
• ptrs tooling
• Parsing, Applying, and Serializing Args
• First pass server state management (i.e. from args and state file) for obfs4.

I am merging this to solidify those things into main, also I am going to use a separate branch to work on the lyrebird binary in a more focused way.
