+Subject: [PATCH] drop the six dependency
+
+six is a Python 2 compatibility shim and rouge-score does not need it on
+Python 3: map, range and zip are builtins, zip_longest comes from
+itertools, six.iteritems and six.iterkeys are the dict methods, and the
+six.ensure_str call sites are all passed str already.
