Deoldify Vapoursynth filter

[Selur]

Atm. one can either use:
1. a preset with HAVC_main which wraps: HAVC_ddeoldify + HAVC_deepex (optional) + HAVC_stabilizer
or
2. (custom) HAVC_ddeoldify + HAVC_stabilizer

Yes, I could adjust Hybrid to convert 'custom' to HAVC_ddeoldify + HAVC_deepex (optional) + HAVC_stabilizer, but I think this is overkill.
Like I mentioned time and time again, the is all getting too complex, too many parameters,...
Especially since I have to expect there to come an additional xy new parameters with the next release of HAVC/deloldify.

Since this is really bothering me, I thought about removing all the custom stuff and just limit Hybrid to support just the HAVC preset based part.
Problem is, that also annoys the hell out of me (only partially supporting havc/deoldify), I now decided to drop the support for it as a whole.

=> Next Hybrid version will not support HAVC/deoldify any more.
If folks want to use it, they would need to either write their own custom additions to Hybrid or write their own code in a custom section.
