Deoldify Vapoursynth filter

[Dan64]

  I don't have added the preset "Custom", but I expected the the GUI will add this option, in this case the GUI should enable the full list of parameters as currently implemented.

Maybe I should instead better drop the custom mode,... 

For QTGMC the "Custom" preset allows to modify a lot of parameters. 
I don't understand the reason to drop the support to "Custom" mode for vsdeoldify since has been already developed.

I forgot to add the support to fp16 in the new function ddeoldify_main()

def ddeoldify_main(clip: vs.VideoNode, Preset: str = 'Fast', ColorFix: str = 'Violet/Red', ColorMap: str = 'None', enable_fp16: bool = True) -> vs.VideoNode:

I attached the updated RC2.
