Remove group. Change area to functionality.

This is to make sense with MR lab-opis!16 (merged) and nice/guis/ansible/ics-ans-role-wp12-opi!6.

So categoriztion doesn't use groups anymore and is not by physical position, but by functionality.

Not sure if "gauges and metrology" is the best categorization but I couldn't fit this in any pre-existing category. I hope if future devices are added we can categorize it better.
