Fix dsd-fme protocol flags, device label, and add tuning controls

Browse Source 
dsd-fme remapped several flags from classic DSD: -fp is ProVoice (not
P25), -fi is NXDN48 (not D-Star), -fv doesn't exist. This caused P25
to trigger ProVoice decoding and D-Star to trigger NXDN48. Corrected
flag table and added C4FM modulation hints for better sync reliability.

Also fixes: device panel showing "DMR" regardless of protocol, signal
activity status flip-flopping between LISTENING and IDLE, and rtl_fm
squelch chopping the bitstream mid-frame. Adds PPM correction and
relax CRC controls for fine-tuning on marginal signals.
