Deoldify Vapoursynth filter

[Selur]

Did a few tests, can't beat the cv2 version in speed.
AdaptiveMerge3 can be speed up a bit by using something like

def AdaptiveMerge3(clipa: vs.VideoNode = None, clipb: vs.VideoNode = None, clipb_weight: float = 0.0, luma="limited") -> vs.VideoNode:

    yuv = clipb.resize.Bicubic(format=vs.YUV444PS, matrix_s="709", range_s=luma)
    yuv = core.std.PlaneStats(yuv, plane=0)
    clipb = core.std.CopyFrameProps(clipb, yuv)
    #Vapoursynth version
    def merge_frame(n, f):              
        clip1 = clipa[n]
        clip2 = clipb[n]
        luma = clip2.get_frame(0).props['PlaneStatsAverage']
        #vs.core.log_message(2, "Luma(" + str(n) + ") = " + str(luma))
        brightness = min(1.5 * luma, 1)
        w = max(clipb_weight * brightness, 0.15)
        clip3 = vs.core.std.Merge(clip1, clip2, weight=w)  
        f_out = f.copy()
        f_out = clip3.get_frame(0)
        return f_out
    clipm = clipa.std.ModifyFrame(clips=clipa, selector=merge_frame)
    return clipm
        
clip = AdaptiveMerge3(clip, org, 0.5)

Side note: AdaptiveMerge4 uses different values.
it uses:
hsv[:,:, 2] = value of 'V from HSV' = max(R, G, B)
vs.
PlaneStats(yuv, plane=0) = luma value Y from YUV = 0.299R + 0.587G + 0.114B.
Both are describes as brightness, but represent different things.
