We need robots

Departures is indexing hundreds of links now, and I can't keep manually checking which ones are open or full. We need robots.

Created a NodeJS script to go through our links in Airtable, check whether the TestFlight is open or not and change the record accordingly.

Put the script into CircleCI so links are crawled on a schedule.

Now when the site builds it will more accurately reflect whether the TestFlight is open and available to join.
