sjg d5b1b6f020 [fix](trx-backend-soapysdr): widen WFM IQ filter to preserve RDS subcarrier ...

The FIR LPF cutoff was audio_bandwidth_hz/2; with wfm_bandwidth_hz=75000
this gave 37.5 kHz, stripping the 57 kHz RDS subcarrier before FM
demodulation. Clamp the IQ filter bandwidth to at least 130 kHz (cutoff
≥ 65 kHz) for WFM so the RDS subcarrier always reaches the decoder,
regardless of the configured audio bandwidth.
