Practice session auto start and stop based on metronome

Add an option that pauses and unpauses the practice session timer with metronome off and on instead of having to manually pause the session.

Hi, can you explain what the value of this would be? It seems it would just cut the session unnecessarily shorter because just because you quickly paused your metronome doesn't mean you stopped practicing? The app already records metronome time vs general practice time. The app also automatically ends sessions after inactivity for 1 hour (if it was start by playing the metronome).
