SensoDrive sometimes suddenly shuts off

[lflipse]

Describe the bug
Sometimes unexplainably, the sensodrive shuts itself of without warning.

To Reproduce
Steps to reproduce the behavior:
Drive long enough and suddenly the thing does not work. You can reproduce this bug by manually shutting the sensodrive off after pressing play.

Expected behavior
Nothing, but fixed it now that an exception is raised. See the joansensodrive.py file, function capture_sensodrive_turned_off().

Additional context
Does not seem like much of a problem, but this happened during an experiment and that means one trial gave useless data.
