Add support for zero phase peaking filter

2

The peaking filter we have today changes the phase. It would be nice to have a bool argument for making it zero-phase.

And maybe rename it to `PeakNormalization`

nara_wpe, like like in https://lhotse.readthedocs.io/en/latest/_modules/lhotse/dataset/signal_transforms.html

The current default masks too much on average

Implement phase augmentation

1

A transform that rotates the phase of each frequency bin [PhaseAug: A Differentiable Augmentation for Speech Synthesis to Simulate One-to-Many Mapping](https://arxiv.org/abs/2211.04610)

Audio transmitted via bluetooth can sometimes be compressed with LC3. Let's make a transform that simulates this lossy audio encoding. https://github.com/google/liblc3

* Deprecate (and later remove) min_amplitude and max_amplitude in AddGaussianNoise * Add min_snr_in_db, max_snr_in_db, min_absolute_rms_db, max_absolute_rms_db and mode * Deprecate (and later remove) AddGaussianSNR

Make BaseWaveformTransform able to pad transform outputs that have a different length

2

This is a prerequisite for transforms that change the length, like [time stretching](https://github.com/asteroid-team/torch-audiomentations/issues/68)
