Added multi-resolution spectrogram module

[wbenoit26]

Adds a transform that computes a single spectrogram by calculating multiple spectrograms at different resolutions and taking the maximum each corresponding pixel.

• Add shape checks
• Add tests
• Finish writing docstring
• Allow specification of more parameters than just n_fft

@EthanMarx Are you aware of any issues that might come from bumping our torch version? Looks like torchaudio 0.13 is incompatible with python 3.11, but the next version of torchaudio requires torch > 2.0

Look good, might also be worth adding a warning with warnings.warn if the total number of spectrograms is larger than some value since we see some pretty poor computational scaling.

Assuming all of our tests pass I don't think so. If anything, it would affect downstream projects. I guess this is a good reason to keep it in dev for a bit until we see potential issues.
