ArcGISFeatureServiceExporter transformer for feature service download

Reading a feature service can take a while, but getting the data state is valuable if you’re doing change detection or a bulk copy.  The ArcGISOnlineConnector does not support download of a feature service item.  This idea is for a transformer that uses the asynchronous export capability of hosted feature layers to deliver a download, such as file geodatabase, for downstream processing.  For example:  https://community.esri.com/t5/arcgis-data-interoperability-blog/etl-pattern-avoid-serializing-bulk-i-o/ba-p/1542004
