Add Mars-Semi MR97310A format

From: Kyle Guinn <elyk03@xxxxxxxxx>

Add a pixel format for the Mars-Semi MR97310A webcam controller.

The MR97310A is a dual-mode webcam controller that provides compressed BGGR
Bayer frames.  The decompression algorithm for still images is the same as for
video, and is currently implemented in libgphoto2.

Priority: normal
