[Feature] Automatically restart tracking on crash

Occasionally the Tracking freezes/crashes and the console output is spammed by the following likes (about 1 entry per second)

[INFO] Discarding the serial buffer (34204 bytes)

I noticed it's enough to press the "Save and Restart Tracking" button and everything works fine again.
Maybe add a mechanism which detects that something is wrong and restarts the tracking automatically.

Hm it doesn't always seem to be the case when the discarding logs are being written, that the camera froze
