Because of the joins required this report performed very poorly using the API as the number of sessions and offerings in a course grew. Instead we can use our GraphQL API to get the data we want from the course down and significantly improve the performance.
I didn't DRY this up, we probably need to replace the reporting service for download and re-use the data fetching in the subject components, but that is for another day.
