RealSenseIsolate class
An isolate to read RGB, depth, and colorized frames from the RealSense.
While using the RealSense SDK for depth streaming, OpenCV cannot access the standard RGB frames, so it is necessary for this isolate to grab the RGB frames as well.
Since the RealSense is being used for autonomy, certain settings that could interfere with the autonomy program are not allowed to be changed, even for the RGB camera.
