ProPainter Vapoursynth filter

Same test I ran in #9 is slower now.
Before I got:

encoded 192 frames in 50.79s (3.78 fps), 1707.74 kb/s, Avg QP:21.51

now I get:

encoded 192 frames in 87.40s (2.20 fps), 1707.83 kb/s, Avg QP:21.45

Okay, strangely commenting out the '@torch.inference_mode()'-lines gets speed up to 3.8fps again.
Side note: Additionally, increasing ref_stride to 100 increases speed to 3.99fps, increasing raft_iter to 30 does slow down the encoding to 2.02fps.

Keeping the '@torch.inference_mode()'-lines and using ref_stride=100 increases the speed to 5.14 fps.

Ps.: did a small test with a non-transparent logo (see attachment)
