Enable gps

On my shift6mq gps isn't working out of the box wit postmarketos. This script enables gps nmea output. Don't know if it need to be nmea, but it works for me.

It will also drop the output of the gps every second at the end. Just kill it with Ctrl + C

To start gps just execute the script:

./gpshelper.sh

After you think the nmea messages doesn't look weird anymore kill it and open for example puremaps or osmin.
Enoy it!
