Add support for 10/12/14/16 bit bayer formats into
This is useful e.g. for validation of various v4l2 devices, which now generate more than 8bit
bayer data, but there is no easy way to convert them into something viewable. Add the support
for it. Bayer data above 8bpp are converted into
RGBA64 to retain precision.
