WebSocket and more simplifications

• Moving towards making this simpler to setup, no more sounddevice dependencies or docker compose files. Just launch the container and test.
• Brought my own Spotify tool back into the mix after being disappointed in the HA implementations. Fallsback to HA options if not configured within Fulloch.
• Lots of testing of models to see what might work on other machines, CPU only etc. Still a lot of work here to be done.
