[5pt] SPCO2 is mapping at the wrong location

[CarsonPruitt-NOAA]

The USGS lat/lon puts SPCO2 in the wrong location, but the NWS data is correct. I thought that since we use nws_preferred, we should be pulling the correct coordinates, but FIM v6 is still in the wrong location. This is in HUC 11110101.

I suspect that there's something going wrong with this step that results in the USGS datum being chosen, but everything in WRDS points to the source of the flow thresholds to be NRLDB. Maybe there's a bug upstream of here.

	datum_data = usgs_datum_info
	elif rating_curve_source == 'NRLDB':
	datum_data = nws_datum_info
