Use RustiCL driver to enable Raspberry Pi 5 to use OpenCL

[rrhan0]

Describe the requested feature

Camera can do 5 fps now because it has been changed to output an 8 bit per pixel Bayer format. It previously used the "debayering core" inside the camera to convert the 8 bit Bayer into 24 bit BGR8. Trying to demosaic on the raspberry pi uses too much CPU, causing massive packet loss. Hopefully using the GPU will decrease the load. OpenCV has demmosaicing support for OpenCL and CUDA. Raspberry Pi 5 uses a VideoCore VII GPU. It did not support OpenCL until RustiCL added support for the GPU. This may allow the pi to do 5 fps rgb video. We should also test an SBC with GPU that has better support for OpenCL/CUDA. If all else fails, we will have to do demosaicing on the ground.
