Withings scale CO2, battery level

A follow-up on this question: Withings scale, temp and Co2

Please add either a separate service or an add-on to the existing withings service to also get CO2 and battery levels. The project here GitHub - dhayab/homebridge-withings-air-quality: Homebridge plugin that exposes air quality data from the Withings WS-50 Smart Body Analyzer is probably a good starting point.

Thanks!
