Focused on the python tooling, automation of:

It looks like this can be pretty easily accomplished with Actions but we'll probably want to hold off until #152 is merged. That PR significantly changes the requirements + process for running the Python test suite; not really much point in setting up Actions for some other approach when it's just gonna be changed once 152 hits.
