Translate FP1 radar action to occupancy

Fixed it with some help from New Aqara Human Presence Sensor FP1 - #291 by liviu

template:
  # up to 9 separate regions
  - trigger:
      - platform: template
        value_template: "{{ states('sensor.living_room_radar_action').split('_')[1] == \"1\" }}"
    sensor:
      - name: fp1_z1
        state: >
          {{ trigger.to_state.state.split('_')[-1] }}
