Deoldify Vapoursynth filter

[Dan64]

Hello Selur,

   you are right, I added these parameters in the past but I never released a new version.
   My intention is to rework completely the scene change methodology.
   I was thinking to use PySceneDetect , but I had no time to test it till now.

   I released a new RC2 to fix some problems related to the max_memory_frames.
   For unknown reasons the memory usage of ColorMNet in Vapoursynth increase exponentially, while if the same code is called in a python script (using frames saved on the disk) the memory usage is very low as described in the paper. But in Vapoursynth it is a nightmare, because this filter is taking advantage for using the frames memory and I had to adapt the code to force the filter to use only a limited number of frames.
   I don't have understood the reason. There is nothing on internet about this problem and it is not possible to fully debug Vapoursynth scripts.
   For the moment I found this solution.
   My be I will be able to improve the memory management, but for the moment this is the only solution that I found (try to set max_memory_frames = 0 to see the problem).

Thanks,
Dan
