Add Reverse and VideoMode Chameleon config params

 - ReverseX/Y params flip the image as expected. This changes the pixel
 format accordingly (e.g. BayerRG8 -> BayerBG8 for an X and Y flip)
 - Video Mode options can affect effective resolution, frame rate and
 brightness depending on camera model, please check the documentation.
