Refactor Camera Drivers

[waltermwaniki]

Issue
Base Camera and subsequently device specific Camera drivers do not inherit from the base VoxelDevice class.
Base Camera should subclass ABC and utilize @abstractmethod to enforce a clear blueprint for voxel compliant cameras.

Solution
Refactor the base camera class.
Refactor individual camera drivers to implement the new base camera class.

I'm trying to resolve the methods and properties that should be listed in the camera base class. I have put together a markdown file in the cameras folder that lists these out. Hoping you can take a look and give me feedback. I left out some properties at the bottom of the readme file that I'm most unsure of.
Currently working in the following branch: Camera refactor 2
