Deoldify Vapoursynth filter

[Dan64]

I released a new version: https://github.com/dan64/vs-deoldify/rel...tag/v1.1.3

I added conversion of clip format to RGB24 when necessary. 

In this way you can revert the changes applied in Hybrid to handle the special case GRAY8.
I can imagine that managing the conversion for all the filters in Hybrid is very complicated.
My approach to problems is to not complicate things unless absolutely necessary.

Thanks,
Dan
