OpenWeatherMap + TaxJar Integration

Wire OpenWeatherMap's other events into TaxJar's other actions so handoffs stay automatic.

Example: when TaxJar's "Watch Customers" fires, WEXTL can "Create Station Measurement" in OpenWeatherMap. OpenWeatherMap has 33 actions (including Create Station Measurement, Create Weather Station, and Delete Weather Station); TaxJar has 21 actions (including Calculate a Sales Tax, Create a Customer, and Create an Order Transaction).
