Pull request overview

This PR adds a GPS acquisition check to prevent attempting to retrieve the home position when the drone has not yet acquired a GPS fix. The implementation tracks whether GPS has ever been available using a flag set when GPS_RAW_INT messages indicate a fix, and returns an early error from getHomePosition when GPS has not been acquired.

Changes:

• Added has_had_gps boolean flag to Drone class to track GPS acquisition status
• Modified GPS_RAW_INT message handler to set flag when GPS fix is detected
• Added early return in getHomePosition() when GPS has not been acquired
• Updated JavaScript error handling to silently ignore GPS-not-acquired errors using sentinel value -1
