Deoldify Vapoursynth filter

[domb84]

I'm using native vapoursynth rather than hybrid but I'm already using grayworld to perform a whitebalance that removes the cast before merging. of course the destroyed skintones still remain which the merge doesn't do enough to resolve, but also takes out the colour that remains.

Sure here's an "uncompressed" sample. I have no idea what is throwing the white balance across these scenes but you can see how severe it is in the cut.

Here's the vs script. I saw some information regarding Softlight, but I cannot understand from the docs how to utilise that to eliminate the colour cast.
