Two new adapters for wildfire data from NIFC WFIGS:
- wfigs_incidents: Active fire incident locations
- wfigs_perimeters: Active fire perimeter polygons
Features:
- IRWIN GUID dedup via is_published/mark_published
- Fall-off detection with removal events when fires exit current
- Bbox post-filtering with shapely polygon intersection
- Severity mapping from DailyAcres (0-4 scale)
- Subject hierarchy: central.fire.<layer>.<state>.<county>
Ships disabled by default; operators enable via GUI.
