Deoldify Vapoursynth filter

[Dan64]

I am not totally against changes in the GUI if they are functional and improve the use of the filter, which is very complex to use. 

I understand that HAVC 5.0 has introduced a number of significant changes and the GUI has already been totally changed since version 4.8.

I hope that a situation of stability can be achieved with the next release of the GUI.
