HDR encoding

[mparade]

Can't be done in Hybrid atm. since Hybrid doesn't use Avisynth+, in case it is possible in Vapoursynth I could adjust Hybrid to support it when Vapoursynth is used.

Ps.: Quick code check: FFmpegSource wouldn't be used for high depth input since it always outputs 8bit.

Please let me know if you were successful with Vapousynth. I would really appreciate if you could make Vapoursynth to support main10, main12 GPU assisted decoding via DGDecNV.
I do not know Vapoursynth, I did not even know Hybrid supported that, so in case of success I would need some support what to change in Hybrid to work.

This means my last test encode to main12 is "damaged". I will encode both SD, HD sources to main10, UHD sources to main10/12 hopefully with your Vapousynth and DGDecNV. They are my only hope.
