aioboto3 package dependency/install

[vtoyedens]

My colleagues and I are working on making some heliophysics analysis packages cloud aware. One of these packages uses cdflib (pySPEDAS) and it is a great experience, particularly since cdflib already has s3 awareness.

We were wondering if it’s possible to add boto3 or aioboto3 (these packages allow for interacting with AWS) as part of the pip install of cdflib. Currently cdflib does a try/except import boto3, however without the package install that import is usually not available. It makes for an awkward experience when calling from another package and it doesn’t make a lot of logical sense for the wrapper package (pySPEDAS) to enforce the boto3/aioboto3 install when it only uses it as a part of the cdflib internal call. The preference would be for aioboto3 since it encompasses boto3 and allows for asynchronous calls.
