Fire index value sensor

I've been monitoring the data and it's been bang on. It's even picking up that I'm in a small higher risk pocket!

One addition that might be useful is a fire risk level sensor, or maybe that value can just be included as an attribute to the fire index sensors. Most people won't understand how the fire index correlates to the more meaningful risk level. I suppose this could be covered in the docs as well so one could just create their own template sensor if needed.

The OpenUV integration does something similar.

I've already done it in a template for myself.

template:
  - sensor:
      - name: "Fire Risk Level"
        unique_id: fire_risk_level
        icon: mdi:fire
        state: >
          {% set level = states('sensor.pirateweather_fire_index') | int(-1) %}
          {% if level >= 30 %} Extreme
          {% elif level >= 20 %} Very High
          {% elif level >= 10 %} High
          {% elif level >= 5 %} Moderate
          {% else %} Low
          {% endif %}
        availability: "{{ is_number(states('sensor.pirateweather_fire_index')) }}"

This is how I end up displaying it in the HA ui.
