Deoldify Vapoursynth filter

[Selur]

Okay,...
I do not seem get the whole 'DeepExMethod' thing.

:param DeepExMethod:        Method to use to generate reference frames.
                                        0 = HAVC (default)
                                        1 = HAVC + RF same as video
                                        2 = HAVC + RF different from video
                                        3 = external RF same as video
                                        4 = external RF different from video

RF = reference frame?

The main idea is to use HAVC_deolddify as a source of "exemplar" frames for "Deep-Exemplar-based Video Colorization" but at the same time to keep the use of HAVC_deolddify in "standalone" mode as in the version 3.5.x.

"exemplar" frames <= are these what you call RF ?

From the looks of it, I won't add 'DeepExMethod' and 'ScFrameDir' to Hybrid.
Don't see how to properly add these to Hybrid in a meaningful way while making sure they are used as intended.

=> I'll add "EnableDeepEx, DeepExPreset, ScThreshold, ScMinFreq" to HAVC_main.
These setting will not influence the 'custom'-mode at all.

I'll remove: dotweak, dotweak_p, degrain_strength from 'custom'-mode.
