Deoldify Vapoursynth filter

In the new RC4, the following plugins: Retinex.dll, MiscFilters.dll, ReduceFlicker.dll
Will be automatically loaded by HAVC as needed.
It is not necessary that you add the loading of these plugins in the script.

Okay,.. sounds like a bad idea to me, but no problem.
I assume that you will only implement the autoloading for Windows.

MiscFilters: still hoping https://github.com/adworacz/zscene will be changed to not require an external call,...
