Create ophy device for andor2 detctor

[Relm-Arrowny]

Acceptance Criteria

• Create an ophy device for Andor2
• 1. The detector should be stageable
  Able to change Acquistion setting, exposure time trigger mode, eg things that need to be change during each data collection
• 2. Should be able to change Andor Diver setting, chip temperature readout time etc.
• 3. Should be able to write data to somewhere.
• 4. Ability to access arr of the image for data visualisation?
• 5. should be able to be use in bluesky plan.

Tasks

• Test what functionality of the detector has using epic PV, eg does the roi work etc etc.
• Go through the device on i22 to draw up a proper task list. (see Ref #332)
• Create the device
• Add extra functionality that needed in drivers like pilatus_driver.py
• A controller much like pilatus_controller.py to deal with how the data collection is done setting trigger, count time etc....
• Device unit test
• Controller and drivers test is required. example
• IRL test
• Should be able to produce images with different exposure time, change all the setting that are required for the image itself.

Things already exist:
Base class for area detector ad_base.py:
struct DetectorState
Globe DEAULT_GOOD_STATES
ADBase class with NDArrayBase (which handle the arr part of the detector) setup the signal part of the epicPv
ADBase itself deal with data acquiring
Globe function start_acquiring_driver_and_ensure_status :
check status and start acquire data and check status again
ADBaseShapeProvider just get the shape by overloading ShapeProvider
