Deoldify Vapoursynth filter

[Dan64]

yes, it is called in HAVC_ddeoldify(), in this piece of code

scenechange = not (sc_threshold == 0 and sc_min_freq == 0)

    clip = SceneDetect(clip, threshold=sc_threshold, frequency=sc_min_freq)

    frame_size = min(max(ddcolor_rf, deoldify_rf) * 16, clip.width)  # frame size calculation for inference()
    clip_orig = clip;
    clip = clip.resize.Spline64(width=frame_size, height=frame_size)

    clipa = vs_sc_deoldify(clip, method=method, model=deoldify_model, render_factor=deoldify_rf,
                           scenechange=scenechange, package_dir=package_dir)
    clipb = vs_sc_ddcolor(clip, method=method, model=ddcolor_model, render_factor=ddcolor_rf, tweaks_enabled=ddtweak,
                          tweaks=ddtweak_p, enable_fp16=ddcolor_enable_fp16, scenechange=scenechange,
                          device_index=device_index)

I included a new RC16 where I anticipated the check in HAVC_main().
