Add support for `Freeze` sensor type

[XaF]

Sensor information

• type: Freeze
• Home Assistant device class: cold
• Panel sends sensor status updates?
  • Yes, I can see the Open/Close messages (I have been able to capture ZONE_ACTIVE messages)
  • No, it seems to only tell us the sensor exists, but never update its state

Decision

Will add / Won't add ? ✅
