First public release unifying landslide, flood, avalanche and weather alerts

A comprehensive Home Assistant custom integration that provides Norwegian weather and geohazard warnings from multiple official sources:

• Landslide, Flood, and Avalanche warnings from NVE (Norwegian Water Resources and Energy Directorate)
• Weather alerts from Met.no (Norwegian Meteorological Institute)

All warnings unified in a clean, modern Home Assistant interface with automatic icon display and rich alert data.

Features

Warning Types

• Landslide warnings (NVE/Varsom.no) - Jord- og flomskredfare
• Flood warnings (NVE/Varsom.no) - Flomvarsling
• Avalanche warnings (NVE/Varsom.no) - Snøskredvarsling
• Weather alerts (Met.no) - Meteorological warnings (wind, rain, snow, etc.)

Version 2.0.0 introduces breaking changes that require migration:

• Integration renamed: varsom → norway_alerts
• Domain changed: All entity IDs will change from sensor.varsom_* to sensor.norway_alerts_*
• New warning types: Met.no weather alerts now available alongside NVE geohazard warnings
• Architecture change: One sensor per warning type (previously supported multiple types per sensor)

Migration Steps:

1. Remove the old varsom integration completely from Settings → Devices & Services
2. Delete any automations or dashboards referencing old sensor.varsom_* entities
3. Install norway_alerts integration (via HACS or manually)
4. Add integration for each warning type you want to monitor
5. Update automations and dashboards with new entity IDs

What's New:

• Met.no weather alerts integration (CAP-formatted data)
• Improved configuration flow with conditional fields
• Better county support (updated for 2024 Norwegian administrative structure)
• Enhanced attribute structure with warning-type-specific fields
