Vmxm fast grid scans

[olliesilvester]

To do:

• Smargon shouldn't be required by the plan -we currently only use the omega motor, and that's only to set it to 0
• Think about putting snapshots to ispyb. Currently, GDA can just send them over. Fastest short team solution would just be for the entry plan to push these to ispyb before doing anything else. Long term solution is to actually take the snapshots in bluesky
• Stop defaulting parameters to i03 and instead make them required - eg beamline and insertion_prefix
• Make sure detector isn't asked to move during gridscan. Vmxm move their detector manually only
