Add average well-being to population counter, or add well-being sensor

I would like to automate Earth Recultivator to auto-launch whenever average well-being falls below a given value, since that is my condition for manual launches as well when settlements are more or less finished and other well-being metrics don't change much anymore. Thus please add average well-being as a metric to the population counter.

Alternatively, there could be a dedicated well-being sensor with more granular metrics, which might help with optimizing well-being under various circumstances.
