Extend Andor iDus/DU camera driver

[thangleiter]

This PR significantly extends the capabilities of the Andor iDus camera driver. A fairly large part of the SDK is now covered.

Since the central data parameter, ccd_data, is dynamic in that it returns different shapes of arrays depending on the acqusition and read modes, I dropped the spectrum moniker. However, this also means that backwards compatibility is broken. If this is something we want to avoid, one could add a DelegateParameter that issues a deprecation warning when called.

To Do

• Test hardware triggering
  Deferred to a later point in time.
• acquired_pixels needs to be aware of downsampling that, e.g., image mode performs.
• acquisition in kinetics mode with the cosmic ray filter turned on errors.
  This seems to be a camera feature, so users should handle it.

Missing Features / Needs testing

• Live stream of the CCD data using the run till abort mode. This requires some async work, but would be nice to have since taking a single picture at a time (1 or 2d) has quite a lot of communication overhead, meaning the fastest update rate I could achieve was ~200 ms.
• Shutter modes (feature not available on our camera)
• More real-time filter modes (feature not available on our camera)

I think this is ready to go for now. I'll postpone work on hardware triggers until I have more time.

Do we add a newspiece here in this repo as well?
