SFMS: Snow Mapping as a Data Service

Ticket 1: Download snow cover data, create a mosaic grid, look at storing this in S3
- [x] #3254
- [ ] show in dashboard
- [ ] Daily data download

Ticket 2: use snow coverage data as a mask for HFI data we receive from SFMS
- [x] #3255
- Mask Fuel grid go into calculation of HFI
- Ability to take out layers of areas under snow
- PMTiles? Spatial Raster?

Ticket 3: Data Service backend of snow mapping
- [ ] #3256
Creating PMTiles layer for consumption in our applications
create raster geo tiff in … spatial ref for other people to use
Can choose multi spatial ref (stick with standard proj for prov?), or lambert conformal (LCC)
How do we want to share? DL from S3, User specify end point direct file download
- Seasonal Fuel Grids for Fire Modelling
- Feature service to do geospatial operations with data
- Future archive fire season (1 fire season), storage?

No files, tests, or entry points are named. Review the completed and open work in tickets #3254, #3255, and #3256, then trace the existing snow data and HFI workflows. Done requires resolving the listed download, masking, raster or PMTiles, spatial-reference, storage, and sharing requirements.
