Deoldify Vapoursynth filter

[Dan64]

I released the new RC5

Main changes:

1) the "B&W mode" "ScaleAbs + Simple(RGB)" should be renamed in "CLAHE (luma) + Simple(RGB)"

2) In HAVC_main I added the parameter FrameInterp (integer), the meaning of parameter is the following

:param FrameInterp:         This parameter will allow to enable the frame interpolation. This method will use
                             Deep-Exemplar to interpolate the colored frames. If = 0, the interpolation is disabled,
                             if > 0 represent the number of frames used for interpolation. The quality of
                             interpolation will decrease with the number of frames, suggested value is 5.
                             Range [0-10], Default = 0

Using this approach it is possible to speed-up the coloring process by 30%-50% (depending on the settings) without significant color loss.
