RESNET ceiling fan algorithm needs current month average drybulb temperature

[nealkruis]

CSE creates probe-able values for several drybulb statistics, but not the current month drybulb temperature. This is required to model ceiling fans according to the RESNET 301 standard:

A daily ceiling fan operating schedule according to Normative Appendix C.4 Table C4(5) shall be assumed in both the Reference Home and the Rated Home during months with an average outdoor temperature greater than 63 ºF.
