* Fixed issue when using Sonar samplers in normal sampling nodes/via stuff like `KSamplerSelect`.
* Add `pyramid` (non-high-res) noise type.
* Allow selecting `brownian` noise in custom noise nodes (but it won't work with `NoisyLatentLike`).
* Use `brownian` as the default noise type for `SamplerSonarDPMPP`.
* Make overriding the selected noise type in Sonar samplers a warning instead of a hard error.
* Improve noise scaling (may change seeds).
* Add `KRestartSamplerCustomNoise` if the user has a recent enough version of ComfyUI_restart_sampling installed.
* SonarPowerNoise: WIP
* don't allow highpass > lowpass
* fix filter unit gain
The filter was computed as an amplitude gain map. This change computes energy
gains instead. This makes easier to ensure unit-gain and makes the alpha values
more in line with literature where the power spectrum is obeying the power law.
new alpha = old alpha / 2
Also fixes the gain of common_mode.
* allow stretch < 1.0, paramter range fixes
* rename lowpass/highpass to min_freq/max_freq
* remove torch.no_grad wrappers
* add previews
* static seed for previews
