Add CO2 sensor support to SMIBHID

[sjefferson99]

For SMIBHIDs used to drive air filters from space state - add optional CO2 monitor support using Adafruit SCD-30: https://shop.pimoroni.com/products/adafruit-scd-30-ndir-co2-temperature-and-humidity-sensor-stemma-qt-qwiic?variant=32383256035411
Log and record CO2 values every minute and store locally as a rolling window, return from co2 API endpoint.
This can allow a simple web query to ascertain current and recent air quality trend using CO2 as a proxy for other contaminants to understand if the filter is performing relative to occupant count and fresh air sources.

Would allow for support in future enhancements such as:

• Pushing data to be logged long term on SMIB for access via the mongoDB or slack command
• Output to a local display to remove need for phone/computer to query API for current reading
• Ability to set a CO2 alarm threshold with buzzer or speaker, button could be provided for alarm snooze

In development I have opted to go for API presentation over local storage for the MVP feature. Although an async loop is provided that logs the outputs to the console every 5 seconds as a PoC.
It is also built against the SGP30 as I did not have SCD-30 to hand, however the sensor framework is easily extensible and the SGP-30 driver can be added easily on a future enhancement.

Created #277 for local logging functionality.

Created new issues for each of the ideas above to develop from this feature so this can be closed on merge.
