[Feature Request] Add support to vs-ddcolor

[Dan64]

Hello Selur,

   thanks for your suggestion. In my experience "ddcolor" is faster than "deoldify" (with render factor > 20). In "deoldify" using a high render_factor it is possible to reduce the flashing, but in any case has the same problem of "chameleon effect", especially on clothes, shown in "ddcolor". At the moment the best solution that I found is to "merge" ddcolor with deoldify, but the flashing effect introduced is still visible. Unfortunately for "deoldfy" is missing a Vapoursynth implementation.
