Custom `win_len` and `hop_dur` in openSmile python

[nicola-corbellini]

Hi everybody!

From the documentation is not clear to me if it's possible and how to set custom window length and hop factor to compute both low-level and functional features.

I see there are two properties (win_len and hop_dur) in the Smile class that I can set. Yet, I don't understand how to correctly set them and if they will affect the processing at all.

Thank you!
