INRIX XD Analytics: automate monthly download via API

[chunhochow]

Figure out how to use the INRIX API and automate the downloading of XD analytics data weekly

API docs: https://docs.inrix.com/

According to https://docs.inrix.com/, we need to email support@inrix.com to get the API token; this hinges on getting our data use agreement re-signed with INRIX.

At some point, INRIX removed API access, but it is now reinstated as the Data Downloader API
