Deoldify Vapoursynth filter

[Dan64]

This was just an attempt on my part to colorize
If there is another better way, of course I'd better implement it
My goal is to implement the best possible option for this type of video

Ok given that in this case it is possible recover some colors from the original clip, it is possible to use the following strategy:

1) create a colored clip using DDColor only and Retinex, this provides a colorful clip but with a lot of color noise
2) create a second clip with the colors recovered from the original clip, this will provide a more stable even if less colored clip (in practice this clip will substitute DeOldify)
3) combine the 2 clip created previously to obtain a colored clip with stable colors

here the clip the combine the strategy described above
