Feature: Code to select color preset

[AvocadoWasSeized]

On the Kobo Libra Colour, in the developer settings, there is a setting/option called CFA Mode which allows you to change color presets. It would be useful so we can see what preset looks best while in the book and not have to leave to select from the developer options. I noticed that for some manga certain presets just make the colored panels and cover arts a lot nicer to look at and a bit more vibrant.

Would be useful if it can have its own button on the menu for each of the CFA mode options so we can select and switch at will. Sorry if this is already an option or is completely stupid
