Integrate upstream GPS PRs 3624, 3625 and 3626
Port the guarded NMEA buffer, validated RMC clock samples and coordinate bounds from meshcore-dev/MeshCore#3624, #3625 and #3626. Adapt clock admission to retain this branch's signed date limits, bounded loop work, tracker acquisitions, sample consumption, diagnostics and periodic settings.
