Deoldify Vapoursynth filter

[Selur]

Okay, took a look.
Unless I overlook something, this is different from what I suggested. (filtering for deoldify, but keeping the luma details)
=> not implementing this
This is the same as applying the denoising before deoldify which Hybrid already can do, but in Hybrid you can use any denoiser not just KNLMeansCL.
This does make sense when deoldify is used outside of Hybrid, but in Hybrid, adding this seems like a step back.
