Handle multipin

[npat113]

Multipins will require special handling from Artemis and the optical tip centring routine. We need a way of specifying the pin type when loading a sample.

Current offset for tip centring is 50microns, this needs altered to 900 microns for multipin (value may change slightly from this depending on final multipin design).

The X cap on grid size also needs changed to 2200mm (again, subject to change).

This whole process will operate at zoom 1 and in flatfield mode.

Still doing edge detection
Will need to do tip centring in Hyperion

Initial tests done on the multipin_tests branch in bluesky/artemis_v5.1.0. Drew an apparently correct grid (https://ispyb.diamond.ac.uk/dc/visit/cm33866-3/dcg/9787083) didn't get any further as need crystals on the pin.

More testing on 20/07/23

• Put the centres in motor positions in the ispy comment
• Write a script to import into GDA based on centres

#828 is script for the hacky GDA integration
