Is there a way to do this currently? I was trying to access some public datasets on AWS (https://registry.opendata.aws/umbra-open-data/). Just interested in listing and reading (e.g. aws s3 ls --no-sign-request s3://umbra-open-data-catalog/)

from boto3 import Session 
from obstore.store import S3Store
session = Session() # requires credentials
public_bucket = S3Store.from_session(session, "umbra-open-data-catalog", config={"AWS_REGION": "us-west-2"})
list(obstore.list(public_bucket)) # InvalidAccessKeyId

You can set 'AWS_SKIP_SIGNATURE': True in the config: https://developmentseed.org/obstore/latest/api/store/aws/#obstore.store.S3ConfigKey

For anyone following this thread, I'm going to remove the literal anon classmethod for now (i.e. revert #143), and just document how to pass skip_signature=True to create an anonymous store.
