[Bug]: DAAC archive logic not pulling the latest cnm.json

[ngachung]

Environment: DEV and TEST with UDS v8.0.0

When a granule gets cataloged multiple times, there are more than one .cnm.json written to S3. The DAAC archiver pulls the first one without any sorting.

Need to sort. so it pulls the most recent cnm.json. Not a perfect solution, but works better than always pulling first from list without sorting.
