Deoldify Vapoursynth filter

[Dan64]

The new HAVC test version now is Ok.

When you can please add the new HAVC_ColorAdjust parameters: DeFlicker, chroma_resize

:param DeFlicker:          if enabled (True) will be applied the filter ReduceFlicker to the clip,
                           range [True, False], default: False
:param chroma_resize:      If True, the clip will be downscaled before applying the filter to speed up
                           the processing, default = False

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.

Thanks,
Dan
