Add multi-SDR support to WeFax decoder (HackRF, LimeSDR, Airspy, SDRPlay)
Replace hardcoded rtl_fm with SDRFactory abstraction layer so WeFax works with any supported SDR hardware, matching the pattern used by APRS and other modes. RTL-SDR direct sampling flag preserved for HF reception. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
