Describe the bug

The get_collection method isn't able to locate a collection that exists because it doesn't request the specific collection or paginate.

https://github.com/unity-sds/mdps-ds-lib/blob/develop/mdps_ds_lib/stage_in_out/dapa_client.py#L41

What did you expect?

urn:nasa:unity:unity:dev:SBG-L1B_PRE___1 exists in dev but throws exception

File "/usr/local/lib/python3.9/site-packages/mdps_ds_lib/stage_in_out/dapa_client.py", line 62, in get_collection
raise RuntimeError(f'unable to find collection in DAPA')

Reproducible steps

What is your environment?

Replace https://github.com/unity-sds/mdps-ds-lib/blob/develop/mdps_ds_lib/stage_in_out/catalog_granules_unity.py#L51 with new client that retrieves single collection
