Add more sensors

[ajabep]

Added:

• Light Sensor, exporting the current ambient light level
• Carbon Dioxide Sensor and its detection level, put in parameters
• Carbon Monoxide Sensor and its detection level, put in parameters
• Air Quality Sensor using, when ESPHome is exporting these values:
  • Nitrogen Dioxide Density
  • Ozone Density
  • PM10 Density
  • PM2.5 Density
  • Sulphur Dioxide Density
  • VOC Density
  • Overall Air Quality

What may be needed to do in the future:

• Ensure that the Air Quality characteristics are using um/m3 and not ppm.
• Implement the "Peak Level" on CO and CO2 sensors
• Being able to choose the AQI function we want to use. Functions has been designed to allow easily this change. Currently, it uses the European AQI.
• Ensure how to integrate the "Excellent" air quality metric when using the European AQI: it starts at "Good", so, I didn't implement the "Excellent level".
