Change SC to work in the decibel domain
...
This makes the soft-knee function differentiable and the performance
should in theory be slightly higher when using these fast gain<->dB
conversion functions. This also fixes the high-frequency rolloff not
working correctly for the downwards compressors.

💥 Use interior mutability for parameters
...
Instead of the previous technically-unsound approach. While it wouldn't
cause any issues in practice, it did break Rust's guarantees. That was a
design choice after adding support for editors in NIH-plug, but this is
probably the better long term solution.
The downside is that all uses of `param.value` now need to be changed to
`param.value()`.

This fixes a NaN from taking the logarithm of zero, and the lower bins
are not actually compressed when this option is disabled. This is useful
when using tiny window sizes as the first bin will span quite a chunk of
the spectrum.
