updateStreamConfig() that updates the format related fields\nin a StreamConfiguration from a given V4L2DeviceFormat structure.\n\nAdd and override to the toV4L2DeviceFormat() helper that returns a\nV4L2DeviceFormat structure populated from the format related fields in\na StreamConfiguration.\n\nBoth these helper functions will be used in a future commit to simplify\nthe Raspberry Pi pipeline
