Observing system

With the changes to the guide star areas for different beam-switching options we need to check the modified version of the notcam.beamswitch script.

Already existing NOTCam sequencer scripts, both instrument setup scripts and template observing scripts for imaging mode, got a major upgrade. Two new scripts for staff procedures to do through-focus tests and find the rotation center were made. See

The spectroscopy setup scripts still need to be upgraded.
