Deoldify Vapoursynth filter

[Selur]

My thoughts,...
He, he, I would write the code differently (more function definitions).
The

os.environ["NUMEXPR_MAX_THREADS"] = "8"

at the beginning should not be needed, since you later use:

os.environ['NUMEXPR_MAX_THREADS'] = str(n_threads)

btw. have you tested whether it makes a difference whether ddcolor and deoldify are fed with b&w or normal colored content?

Won't get around to adjust Hybrid to this version before the weekend, since it's a lot of changes to add and I'm not that well atm.
Would also be good to add the min/max values for all the list-parameters. Also you should note that for example for sat the first param in the list ist for deoldify and the second is for ddcolor.
