Using S3 as artifact storage location

[mingjerli]

LineaPy is now supporting using S3 as an artifact storage location. We can now work on the same artifact store from anywhere or share our artifacts with anyone easily. It can be achieved by running the following code at the beginning of your session to set both your LineaPy database and artifact storage location:

    lineapy.options.set('artifact_storage_dir','s3://your-bucket/your-artifact-folder')
    lineapy.options.set('database_url','corresponding-database-url')

Of course, we need to make sure both storage location and database are accessible from our machine. To learn more about how to configure these items please see Artifact Storage Location and
