[Feature] sliders for filters #22

Hi. The new filters are nice but the b/w is unusable if there is any shade on paper. I should be able to adjust levels using a slider. Same for magic color. Its right now all or nothing. Adjustable would be so much better

It would be great if we can get sliders for brightness, contrast, saturation, etc and if possible ability to make our own presets.

Is it possible now to force the black and white mode? Open Note Scanner seems to support this.
