Get repo into a maintainable state

[olliesilvester]

There are some tasks we should do to get this project into a more maintainable state:

• Do Convert TODOs from code into issues #2 and Tidy input of jumps, lines, and arcs in plan_stubs.py #10
• Get the branch of dodal merged into dodal main (first, specify what needs to be done for this)
• Add documentation for: Purpose of the repo; how to develop and release changes; where the IOC is installed
• Add unit tests where appropriate, eg for the python parts

Here's a brief list of the changes needed to get the dodal branch merged:

• Create a daq_configuration directory to put the oav parameters in, and use that instead of the OAV.json in dodal

• Use as much of the oav_detector.py as possible instead of the custom OAV made in the other branch, as there's lots of repeated code.

• Same as above with the Robot

• Give the Goniometer device a more specific name based on its functionality. Maybe SixAxesGoniometer or the name of the actual hardware? Consider sharing some of the code that the Smargon uses, to create a base Goniometer class

• Confirm that MJPG_URL_RBV is a valid PV for other beamlines which use MJPG.py. Same thing for robot RESET.PROC

• Create a beamline module (analogous to i03.py or i04.py where we can instantiate devices from, to use in our plans

I probably missed some stuff but this will do for the time being!
