request Album Art color settings in Poweramp widget

[STPeach]

Hi, first of all thank you very much to the developers for this excellent audio player, long time user here and I have nothing yet to complain about Poweramp.

 

That said, I'd like to suggest a new setting in widget customization menu for Album Art color/saturation control.

It's nothing but a aesthetically relevant request yet would improve the way I can personalize my home screen.

 

Quick example would be this home screen, note how well the album art fits with my home screen background, It would be handy to have a Saturation setting to make all my covers look black and white and always fit my screen theme!.
