[PD] [Gem] 10-bit per channel in Gem

afaik, Gem only supports 8bit per pixel images
so all pix_* objects have this limitation
I was wondering the same when working on image capture plugin with 10 or
12bit camera
I didn't find any solution to increase the depth without code refactoring

do it yourself
