libcamera: bayer_format: Add toMbusCode method
This makes it easier to perform transformations on Bayer type mbus codes by converting them to a BayerFormat, doing the transform, and then converting them back again. Signed-off-by: David Plowman <david.plowman@raspberrypi.com> Reviewed-by: Jacopo Mondi <jacopo@jmondi.org>
