Fix get_latents_path to run on windows too

[rodjjo]

What

• Fix a frame counter in get_latents_path function.
• Update readme to instruct how to run using virtualenv on windows.
• Add some file's patterns to .gitignore file.
• Add kornia and av dependencies to requirements.txt
• Add requirements-torch.txt with cuda support.

Why

I was getting an error when the function tried to get the number of frames.

This is the corrected code for Windows OS in
"run_tokenflow_pnp.py"
instead of
n_frames = [int([x for x in latents_path[i].split('/') if 'nframes' in x][0].split('')[1]) for i in range(len(latents_path))]
write this:
n_frames = [int(os.path.basename(x).split('')[1]) for x in latents_path if 'nframes' in x]

Thanks, That works. I guess I can remove regular expressions to make it simple.

still receiving an error in the new code.

Try again, I changed argentinox suggestion a little bit.
