Accelerate FRUX by caching the filters when possible
Allow doing FFT on CPU in FRUX for GPUs that won't work otherwise
Allow disabling normalization in SamplerConfigOverride node
Fix base power and pink noise types.
Other cleanups
* 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.
* Improve NoisyLatentLike to allow calculating strength with sigmas and noise injection
* Update documentation for NoisyLatentLike changes + general improvements
* 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
* README: SonarPowerNoise documentation
