Future: update fire hydrology layers

[amedenblik]

This is an issue for the future.

The National Interagency Fire Council (NIFC) is reorganizing their fire layers. Issue #194 will resolve fire layers to their current status as of June 24, 2022, but NIFC plans to update their layers in the future.

In issue #194, that layer will be marked as "2021 Wildland Fire Perimeters". In the future, that layer will presumably continue more years. There may be updates to other layers as well.
