VAD: Don't pad if padding is not needed

[Purfview]

Avoids appending extra window when audio length is already multiple of window_size_samples

Any Idea why the CI fails? it seems unrelated, I also retried it multiple times

Lets check.

Capping huggingface_hub at <=0.19.4 solved that error.
It's capped at "0.19.4" in my env, I had some problems with some higher version, I don't remember what or why, I'll check what's going on.

EDIT:
Tested huggingface_hub 1.0.1, it downloaded models, looks like it doesn't import "requests" anymore, so I made a separate PR to address that.

But there is new error, so WIP...

merging as the error is not related

So, what to do with this?

1. Leave as it was. [Close PR]
2. Return vad func after empty audio check.

I say we leave it as it was, one more window never hurt anyone
