EQ bands can break audio output and/or crash UI

[Gluton-Official]

Certain EQ band configurations can cause NaN values (likely from a divide by zero) in audio output or a panic from unwrapping a None value when drawing the spectrogram.

Applying a smoother to band frequency, level, and q value might help, but NIH-plug does not support smoothing non-linearly through 0.

Some potential solutions:

1. The initial value range needs to be offset to not contain 0 (though this would require unshifting the range when using the value for calculations or displaying)
2. Smoother would need to automatically shift value ranges if they contain 0 and unshift when retrieving values
