Add RGB blend mode
Currently, for denoise profile for instance, we can blend uniformly on RGB red channel, RGB green channel or RGB blue channel.
It would be awesome to be able to have a blend mode "RGB" that would make appear 3 additionnal opacity sliders (one per channel).
For instance, I usually use 3 instances of denoise profile wavelet with blend modes on red, blue and green with opacity of 80%, 65% and 50% respectively, and I would like to be able to use only one instance instead (this would save computation time, as I have 3 instances only in order to be able to have different opacities for red green and blue. The instances are all identical except for blend mode.).
I would also like to be able to do this for the rawdenoise module, have different opacities for green pixels than for red pixels and blue pixels.
The reason I would like this is that noise is usually higher in red and blue channels than in green channel. Setting different opacities for the 3 channels allow to get very good denoising results.
Thanks a lot :-)

As an example, please find attached a very basic style for denoising, that use wavelets on red, green and blue channels separately.
Having a RGB blend mode would allow such denoising with 2 instances only instead of 4 instances.
