Deoldify Vapoursynth filter

Hello Selur,

  I had time to review the code and add some description of the new functions.
  No material changes but I changed the name of "luma_threshold" in "chroma_threshold" and "scale_factor" in "luma_threshold".
  I attached the last version.

P.S.

Wow, I went through that readme- very interesting results you got there. Great read, and I like the project! Thanks for doing this.
