This PR makes sweeping changes to psub.
Most notably it now supports players other than fflplay using a plugin system. Plugins have been made for ffplay, vlc and mpv though they all need more testing.
There's the starting of a test suite though this too needs work.
Python has been bumped to 3.10 and I'm making use of pre-commit and coverage for better dev flow.
