Apply downwards compression to DC bins
...
In Spectral Compressor. We avoided this because it messes up upwards
compression, but downwards compression is perfectly fine.

Fix disabled DC filter behavior

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.
