Add a photo-sensitivity filter
This adds 2 filters actually: one only adjusting the colors, and the other combining the color adjustment with negative-lightness. These filters are not based on much data but on the feedback from a user suffering from visual strain. The photosensitivity-1 filter is the base transformation, mostly useful in combination with one of the negative filters (negative-lightness would be the go-to recommendation). photosensitivity-1-negative is the same filter but combined with negative-lightness for a ready-to-go experience, which plays nicer with dynamic filter change.
