Power mode (#6)

* add way to turn detrend off. update python api to expose it.

* Add stacked per-axis spectrograms (T, F, C) to senpy API (#5)

* Add StackedSpectrogramResult and compute_stacked_spectrograms to senpy API

Introduces per-axis NUFFT spectrogram stacking along a channel axis:
- StackedSpectrogramResult: container for (T, F, C) spectral tensors
- STACKED_SPECTROGRAM_CHANNELS: default channel list ["x", "y", "z", "mag", "jerk"]
- compute_stacked_spectrograms(): computes independent NUFFT spectrograms
  for each channel (x, y, z, magnitude, jerk) and aligns them to a shared
  time grid before stacking into a (T, F, C) array
- Tests covering shape, channel parity with standalone compute_nufft_spectrogram,
  subset channels, and rejection of unknown channel names

* clean up and optimize

* compute and return norm when spectrogram is requested, instead of copying complex to python and then doing norm.

* clean up and optimize the api. accept version 2.0 is here.

* add note that psd = power already from cpp definition
