manual solution for getting ATL15 s3 urls via icepyx

[JessicaS11]

For the FOGSS workshop tutorial in March 2023 ATL15 s3 urls were needed. Ultimately, this information should be pulled from the CMR metadata, but at this time the s3 urls were not available there. This PR adds a short-term brute-force solution for a very specific ATL15 + cloud use case.
