Add SET in next SDR

[jbrossman]

Hi all, the Weatherization Assistance Program (WAP) would greatly benefit from having standard effective temperature (SET) as an automatic output for the next national/standard data release. SET can be used to show thermal resilience and tie together health impacts from unhealthy temperatures, and therefore would greatly extend the use case of ResStock data for other use cases. Please consider this for the next release.

Use the Pierce Thermal Comfort Model, which would add the SET and other outputs. SET is the hourly integral of degrees above a temperature threshold (86F).

Most useful for homes without cooling. Probably not for partially conditioned units. Unavailable periods new feature.

Probably just adding a line to the YAML file and checking results.
