Null check for GLOS metadata directory (not totally sure this fixes NPE when dir doesnt exist)
Changed metadata database to use H2
Real fix for GLOS nonexistent dir, added source options to example props
UsgsWater: only request states within bounding box
Removed gt-geojson (not needed)
Add state filtering to HADS and RAWS, all station updaters besides non-sos NDBC now have tests (still need to test observation retrievers)
Removed trace.db
Use NDBC SOS in AggregateStationUpdater
