Add i15-1 hexapod motors for crystallography-bluesky#9

[Mark-Booth]

Fixes crystallography-bluesky#9

Instructions to reviewer on how to test:

1. Wait for missing i15-1 motors to be restored
2. Confirm dodal connect i15-1 runs.
3. Confirm which axes are X, Y and Z.

Checks for reviewer

• Would the PR title make sense to a scientist on a set of release notes
• If a new device has been added does it follow the standards
• If changing the API for a pre-existing device, ensure that any beamlines using this device have updated their Bluesky plans accordingly
• Have the connection tests for the relevant beamline(s) been run via dodal connect ${BEAMLINE}

TODO: Confirm X, Y & Z axes are beamline standard

Motors still offline so haven't been able to do dodal connect, but looks good, happy to be merged once naming is addressed

I think a more explicit name here would be good

[jacob720]

Same here

Hexapod is connecting this morning

[EmsArnold]

@jacob720 , with regards to the hexapod being two distinct devices, it looks like symmetrie's naming convention for their hexapods is either X, Y, Z, RX, RY, RZ or TX, TY, TZ, RX, RY, RZ. As more than one of these hexapods exist, it is likely worth creating a hexapod device which can follow these conventions, rather than trying to make the hexapod fit a device like a gonio with X, Y, Z, KAPPA, PHI, OMEGA
