ARANET integration - option to change radon concentration unit of measurement

[schwa (Schwaboy)]

The default unit of measurement for radon concentration on the Aranet integration is Bq/m³. I would like the ability to change this to pCI/L if desired.

Add unit conversion for radon measurement

The HA Airthings integration and ESPHome AirThings BLE integration both currently pull in radon data in units of becquerels per cubic meter, or Bq/m³. In the US, radon is typically measured and evaluated in units of picocuries per liter, or pCi/L. While it’s easy enough to create a template sensor and divide Bq/m³ by 37 to get pCi/L, it would be great if units of radon could be changed via the UI just as other units can be changed as of 2022.4.
