Spotify edpoint checks

[woolfg]

Walk through all api collectors and do:

• [ ] document the spotify api (is is an aggregated api, can be one secific day fetched, should be stored as a historical value if aggregated, etc)
• [ ] Check if all historical data is stored if needed
• [ ] check if date range is correct and api is correctly called in the pipeline and correctly handled in the api (especially specific day apis vs. daily apis which have to be saved "historically")
