Response MediaType CSV failing

[jonaraphael]

Sometimes the CSV format download seems to fail. f=geojson does NOT fail in these same circumstances.

Here it works (4 rows of data):
https://api.cerulean.skytruth.org/collections/public.aoi_type/items
https://api.cerulean.skytruth.org/collections/public.aoi_type/items?f=csv

Here it fails (expect 141 rows of data, but returns 2 rows of garbled data):

@jonaraphael thanks for the report,

It's interesting because using other streaming output format like ndjson seems to work fine

$ curl https://api.cerulean.skytruth.org/collections/public.slick_plus/items?sortby=slick_timestamp&datetime=2023-12-01T00:00:00Z/2023-12-08T00:00:00Z&filter=machine_confidence%20GTE%200.6%20AND%20area%20GTE%2020000000&f=ndjson | wc -l 
10

$ curl https://api.cerulean.skytruth.org/collections/public.slick_plus/items?sortby=slick_timestamp&datetime=2023-12-01T00:00:00Z/2023-12-08T00:00:00Z&filter=machine_confidence%20GTE%200.6%20AND%20area%20GTE%2020000000&f=csv | wc -l

Note:
#160 will be merged an released into a 0.6.0 release but I'll also backport this to a 0.5.* version so you can redeploy cerulean_cloud
