Vapoursynth-BM3DMETAL R2

[yuygfgg]

To encode stuff a bit faster on my poor macbook I made this plugin. Usage is 99% identical to VapourSynth-BM3DCUDA except parameter fast is recommended to be False instead of True.

Vapoursynth-BM3DMETAL is ported from WolframRhodium's VapourSynth-BM3DCUDA. Great appreciation to them for making and maintaining that fantastic work.
