Slight mask optimization

For [L134](https://github.com/Beatrice-Raws/VapourSynth-insaneAA/blob/master/insaneAA.py#L134) it's a little faster to use the built-in parameter `scale=2`. The results are not exact but are ±1 with integer formats so that can be chalked up to...

Processing chroma planes separately as luma is faster

Splitting up the planes and processing them all separately gives me a pretty big speedup. ``` import vsutil clip = core.ffms2.Source() clip = vsutil.depth(clip, 16) a = core.placebo.Deband(clip, planes=1|2|4, threshold=4,...
