The existing implementation of the BayerFormat class supports converting a V4L2PixelFormat to a BayerFormat and vice-versa. Expand the class by adding support for converting a media bus code to a BayerFormat instance, by providing a conversion table and a dedicated static methods. Do not provide support for converting a BayerFormat to a media bus code as there's no 1-to-1 mapping between the two.
