Update __main__.py

Fix MpvMediaPlayer Race Condition
Goal: The mpv library runs in its own thread. When a track finishes, its callback (_on_idle_active) runs in that thread and tries to modify the satellite's state, creating a race condition. We will fix this by "marshaling" that callback onto the main asyncio loop.

added loop=loop to the MpvMediaPlayer constructors
