Test Pilot Event-Based Installation Counts

The output of this notebook is used to fill in the installation counts from testpilot.firefox.com. The way we calculate these counts is:

* Count all the enable and disable events since the switchover to
  event-based pings
* Add all the enable and the disable to our baseline numbers (the
  approximate number of installations we had before moving to event-based
  pings)
* Output these numbers to a publicly-accessible json file (available at
  https://analysis-output.telemetry.mozilla.org/testpilot/data/installation-counts/latest.json)
  -- note we output the results to latest.json as well as <timestamp>.json

Please note these numbers are calculated for the sole purpose of giving an approximation to end-users and should absolutely not be used for decision-making.
