Implement OAK-D Module #37

AbstractCamera handles everything shared already. This task is to implement the two abstract methods that are OAK-D specific, with a few OAK-D specific helpers.

1. Initialize_camera() --> Bool

• Setup the DepthAI pipeline

2. Capture_frame:
   Include rgb, depth, centre-depth as well.

3. sample_centre_depth(depth_frame) -> takes the depth frame and returns the depth value at the center pixel.

4. stop() --> override the device to stop the DepthAI device.

Refer here for examples of previous year's implementation.
