Add ColorProcessing algorithm that is in charge to manage brightness, contrast
and saturation controls.
These controls are currently based on user controls.

Let's shorten the lines with

	auto &cproc = context.frameContext.cproc;

> +	const auto &brightness = controls.get(controls::Brightness);
> +	if (brightness) {
> +		context.frameContext.cproc.brightness = std::clamp(int(*brightness * 128), -128, 127);

		cproc.brightness = std::clamp(std::round(*brightness * 128), -128, 127);

to round to the closest value instead of rounding down unconditionally
(you need to include <cmath>). Same below.

This needs to move to the IPA, I'll send a patch on top.

I think you don't need this header as this algorithm doesn't retrieve
any value from the tuning file.
