[PISW] When motors aren't powered up and calibration is initiated, software hangs

I haven't explored this very much, but you can display processes using ps aux | grep python then sudo kill <process num>. I will look into this later if I have time.

During the calibration, this occurs because there is no error checking in the __move_until_lim(). It is continuously waiting for the motors to move the mount to the optical sensor limits, so if it doesn't get there, software gets stuck in this process.

Ideally, this shouldn't ever happen, but when running in the console menu, it isn't possible to halt with a keyboard interrupt. I have opened an issue about this on the console menu repo and I will link this soon (although the console menu is temporary, so this isn't critical).
