SkyRC GSM-010 GPS Meter Remix

dp106 did a great job

version: SkyRC_GPS_MOD_20190217
-added more space for mounting a strap, it was a littlebit to narrow

version: SkyRC_GPS_MOD_20190202
some things I've added:
-the base is thicker
-added a middle slot, for use with battery straps
-a little more room for fitting the meter

printed this in PLA with 90% infill
