Add frequency-selective attenuation of the L-R difference signal to
reduce stereo hiss on weak FM broadcasts. Uses the quadrature component
(diff_q) as a noise reference per US7292694B2 (Wildhagen/Sony).
The algorithm splits sum, diff_i, and diff_q into 6 overlapping subbands,
estimates per-band SNR from smoothed |diff_q|² noise power, and applies
an energy-weighted broadband gain to the original diff signal. This
preserves clean stereo content (<4 dB loss) while attenuating noise-only
diff channels (>6 dB reduction).
Enabled by default; toggled via set_denoise_enabled() / set_wfm_denoise().
