NMEA Updates

[Wackymax]

This update includes the following changes:

1. Android 34 now includes properties for MSL altitude so we can use that instead of the MSL from NMEA messages when available.
2. We now support reading MSL NMEA messages from other constellations.
3. Always start the NMEA listener so we can include GPS fix data.
4. Upgraded Android packages to the latest versions.
