Take an URL for a S3 object and returns a string with a presigned GET-URL for that particular object. Takes the following options (a map) as the last argument, the map value shows the default values: {:ref-time (java.util.Date.) ; timestamp incorporated into the signature :expires "3600" ; signature expires x seconds after ref-time :region "us-east-1"} ; signature locked to AWS region

By default credentials are read from standard AWS location.
