This program generates a CI report from the gotests.json generated by go test -json (we use gotestsum as a frontend).

We won't generate any report/stats for tests that weren't run. To find all existing tests, we could use: go test ./... -list=. -json, but the time it takes is probably not worth it. Usually most tests will run, even if there are errors and we're using -failfast.

The script fetch_stats_from_ci.sh can be used to fetch historical stats from CI, e.g. for development or analysis.
