Validate reports still work.

With #356 and #365, we'll have a lot more US counties getting included in the baseData.json report. Ensure everything still generates ok, and doesn't time out. (Potentially rewrite this to handle the increased count.)

Have merged in #369 "parallelize base data", which also does recursive get for case data in basedata.json. Will ensure it works in staging and then launch to prod.

timeseries.csv crashes now ... https://api.staging.covidatlas.com/reports/status?format=html

In staging, we hit the max memory for the lambda (3008 MB!!!).

This won't affect the FE, but it will affect anyone using that report.
