Provides a sliding window over a batched continuous raw audio tensor.
Optionally, provides padding (Currently not implemented).
Combine this module with a pre-encoder compatible with raw audio data,
for example Sinc convolutions.

Output length is calculated incorrectly if audio shorter than win_length.
