🛰️ Simple IoT now processes GPS data

Simple IoT now processes GPS data. Three sources are supported:

Serial receiver speaking NMEA
gpsd daemon over TCP
Built-in simulator that generates realistic tracks with no hardware attached

All three publish the same points — latitude, longitude, altitude, speed, heading, fix quality, satellite count — so everything downstream stays the same no matter which one is configured.

Pairing this with VictoriaMetrics for storage and Grafana for viewing makes an excellent combination for edge devices.

gpsd is an interesting project that I've never used before. From the gpsd web site:

GPSD is everywhere in mobile embedded systems. It underlies the map service on Android phones. It's ubiquitous in drones, robot submarines, and driverless cars. It's increasingly common in recent generations of manned aircraft, marine navigation systems, and military vehicles.

See the GPS documentation for configuration details.
