New data source for GDAC from Amazon S3

[gmaze]

As part of “action 48 - admt-21 Argo data on the cloud” GDAC contacted Amazon and its ASDI program (Amazon Sustainability Data Initiative).

There is now a prototype of GDAC on the cloud, updated daily in an S3 bucket.
https://registry.opendata.aws/argo-gdac-marinedata/

The s3 ressource is: s3://argo-gdac-sandbox/

It would be fairly easy to implement a new data fetcher in argopy for this GDAC backed data source

At this point, only the index files are accessible and supported by argopy (#326 )
