Deoldify Vapoursynth filter

[Selur]

please remove any grain from the clip, because it will create artifacts on colored frames.

Maybe adding extending the script with some prefiltering options might be a good idea.
So basically offer a bunch of denoisers (with fixed settings) and then:
1. take source and remember it
2. denoise source
3. feed denoised source to deoldify
4. Merge luma from original and chroma from denoised souce.

Ps.: unless something comes up, I'll release a new version of Hybrid on Sunday.
