"Forcings" (precip/airtemp) grids from NWRFC

Updated sample file: https://www.nwrfc.noaa.gov/weather/netcdf/2022/20221212/QPF.2022121212.nc.gz .

Note: It looks like only current day is posted, so the link above may not be very durable for retrieving a sample file after today. Will have to fiddle the date numbers in the URL.

Sample file contains 6-hour interval grids, covering approximately 10 days into the future. Will add sample file to USACE/cumulus-geoproc-test-data shortly.

DSS result of testing:

Note: We used the NetCDF parameter date_created to set the forecast version on this product. This should be confirmed with the data provider. There is some uncertainty around seemingly different timestamp in the filename ("12.nc").

Example: Sample File QPF.2022121912.nc

Timestamp in GDAL Metadata: 15:30 GMT (image below)
Timestamp from webserver: 7:30 Pacific (corresponds to 15:30 GMT)
Timestamp in filename "12.nc": 12 GMT ? Unsure how this fits with the other two timestamps.
