Parse GGA/GSA fix quality from NMEA, add PAIR command init sequence

Browse source 
Replace altitude-validity heuristic with authoritative GGA quality
field (SPS/DGPS/RTK) and GSA nav mode (2D/3D) via TinyGPSCustom
extractors. Send $PAIR062 commands at boot to filter NMEA output
to only GGA/GSA/RMC/GSV and configure PPS for fix-only pulses.
GpsPayload struct gains fix_quality field (16 -> 14 bytes packed).
