Adjustment merge + new brightness settings (#359)
* add new rgbtransform * activate rgbtransform * integrate new transform and gamma in adjustment, disable transform * fix brighness limit * advance upper and lower thresholds * start removing color transform * adjust configs/schema * implement json for new color adjustment * finish hyperion-remote extension for new adjustment settings * fix typos * rename luminance to brightness fix jsonapi for new adjustment * fix some bugs in adjustments * fix i18n * fix gamma via json * now brighness values goes from 0-1 with 0.5 is the default for all brighness is equal between the channels. less 0.5 all channels scaled down to new brighness, above 0.5 if possible channel gets brighter - but brighness is not equal between the channels anymore brighness value curve is now exponential instead of linear - this feels more natural * hslv cleanup
