HDR encoding

[mparade]

Since decoding through DGDecNV isn't supported atm. Hybrid will use a libav based decoder like FFmpegSource or LibAvSource. Decoding quality should be the same for hardware and software decoders unless one is buggy.

I can probably create a Dev version for testing for you without the DgDecNV restrictions if you're interested.

I would be very interested, perhaps can speed up my encodes significantly.
My card is a GTX1060 using the latest DGDecNV. I know that HEVC format is supported by DGDecNV and my card supports main10 and main12 profiles, so hopefully will be working. 
I really appreciate your help!
