Add HackRF support to TSCM RF scan and misc improvements

Browse Source 
TSCM RF scan now auto-detects HackRF via SDRFactory and uses
hackrf_sweep as an alternative to rtl_power. Also includes
improvements to listening post, rtlamr, weather satellite,
SubGHz, Meshtastic, SSTV, WeFax, and process monitor modules.

Fixes #154
