This commit adds support for monochrome (greyscale) raw sensors. These are sensors that have no colour filter array, so all pixels are the same and there are no distinct colour channels. These sensors still require many of an ISP's processing stages, such as denoise, tone mapping, but not those that involve colours (such as demosaic, or colour matrices).
