#1568 Updates NBFM decoder configuration so user can enable/disable high-pass filter option in the audio module to effect audio playback and audio recording of the demodulated audio. Disabling the filter allows recording of DC and sub-audible signalling that may be present in the demodulated audio (e.g. LTR or squelching signalling). (#1569)
