Determine if we are using the jpeg or YUYV (raw) feed from webcams #228

Raw has less noisy, jpeg possibly faster.

Maybe add an option?

There don't appear to be any OpenCV flags designed to switch this, which is unfortunate. https://docs.opencv.org/3.4/d4/d15/group__videoio__flags__base.html

We might be at the mercy of what ever format the camera returns. JPEG compressed or otherwise.

The solution is not to use the OpenCV API to acquire images -- in libkoki we acquire images use v4l2, having configured the camera's delivery format. It is hard to find webcams that don't support YUYV.
