Gmoccapy: Use calculator widget to edit offset values in offsetpage

might be useful.

Haha really cool that you take this up - this has been in my backlog for almost 3 years now: hansu#5

Some notes:

1. I would keep the behavior that you click "edit offsets" and then you can edit multiple offsets and return by clicking this button again. Now you need to click "edit offsets" for every value you change.
2. I would keep the text in the calculator dialog short like "G59 Z-offset:" instead of "Set G59 Z-offset to:"
3. It would be good if you could preset the current value in the calculator.
   For example if you click of the G54 Z column, the Z-value should be already in the entry like this.
   This would come close to the request in the forum: https://forum.linuxcnc.org/gmoccapy/46488-and-value-feature#249332
