DeepFilterNet 3: cap attenuation (-a 20) to avoid regressions on narrowband/telephone speech

deep-filter at its default full attenuation made 12% of telephone-band earnings-call clips audibly worse (DNSMOS OVRL -0.3 or more, SIG -0.18 mean); the same clips at -a 20 regressed 0% with the same overall gain. --pf made it worse (18%).
