* Removed depthai_tracked_device - now you create a "SLAM" device, plug any frameserver into it and you're done
* Consolidated the grayscale frameservers into just one that gives you SLAM sinks
* Allows for different framerates and half-size for ov9282s
* Added debug frame sinks
* Added the ability to wait at startup for a number of frames for the streams to stabilize before submitting them to SLAM
