Investigate Payload GPS

[breadnmkii]

During the 12/17 Elsberry launch, Payload Electrical was successfully receiving telemetry from their base station. However, the GPS module was outputting incorrect latitude/longitude degree readings.

• [x] Run a simple Adafruit example test code of the GPS module to ensure sensor functionality
• [x] Check Payload main.ino parsing of GPS data

I recall @loganfarrow and I had to do a little bit of weird math to convert the GPS output into actual location readings, so make sure we're doing that

@loganfarrow, @autumnxu, @jiwenofu good work, GPS produces valid lat/long coordinates. May want to look into long fix times as a next improvement.
