It is not sustainable to add a new flag for every new video format
family (eg. YUYV, RGB, NV, MJPEG, etc), so add a formatFamily enum to
indicate these in the FormatConverter.
Note that formats are grouped into families based on if they are able to
share a set of parameters for conversion.

When the camera provides MJPEG, use the QImage JPEG decompression code
to convert that to RGB.

qcam is a sample camera GUI application based on Qt. It demonstrates
integration of the Qt event loop with libcamera.
The application lets the user select a camera through the GUI, and then
captures a single stream from the camera and displays it in a window.
Only streams in YUYV formats are supported for now.
