ZOOM: add mechanism for beamline presets #8888
Description
As a user of ZOOM I would like to be able to hit a button on an OPI and my beamline gets set up correctly for that mode. This will involve setting some jaws to square gaps and some chopper SPs - this can currently be done with a script (to be provided)
This is effectively zoom's equivalent of the collimation on SANS2D, though motion setpoints may not be the best tool for the job as this will be setting chopper values etc.
Technically it could be done in a similar fashion to POLREF's laser on/off using the user buttons
which can call a python script underneath - LC of ZOOM already has this script.
This is slightly linked to #7499 as the buttons need to be displayed on that OPI, but this ticket could be done first by using a separate OPI and linking it via a linking container in #7499.
Acceptance criteria
- User buttons are tied to a script which can set preset values to a number of parameters
- Scientists can easily edit this if needed
- Buttons are added either to a new OPI or to the OPI made by Apply SANS2D Anti-Clash Solution to ZOOM #7499 if done first.
