Formal Protocol for camera interface

Browse source 
I've now split the base camera code into a runtime-checkable Protocol
and a concrete base class (which is optional). This removes the requirement
for cameras to subclass `openflexure_microscope.things.camera.Camera`
and instead uses duck typing that should
work both statically and dynamically.

As part of this, I've moved the commonly-used dependencies
on the camera inside `openflexure_microscope.things.camera` for consistency, and to make it easy to update them if it changes in the future.
