Missing zone handling in iAlarm integration

Current iAlarm integration only provides the alarm_control_panel entity.
Having a sensor entity for each configured zone is missing.
Every zone sensor should have at least the following attributes as available from APIs:

  • ID
  • Name
  • Type
  • Open (entity status)
  • Fault
  • Alarm
  • Bypass
  • Low Battery
  • Ok
