Presently the colour processing component exposes controls for
brightness, saturation, and contrast to the applications which are
handled and processed accordingly on the ISP.

The implementation lacks reporting the values that are set back to the
application.

Utilise the new Quantised types to provide the values that were applied
to the hardware and report them in the completed request metadata.
