tokio-xmpp: add StreamFeatures to Online event

tokio-xmpp/ChangeLog

@@ -5,6 +5,9 @@ Version NEXT:
         new default. The newly-introduced `pedantic` feature can be used to
         opt into the previous default behaviour of rejecting all unknown
         child elements and attributes.
+    * Breaking:
+      - Add `xmpp_parsers::stream_features::StreamFeatures` to
+      `tokio_xmpp::event::Online` (!631)
     * Added:
       - Expose `client_auth` method to allow manual stream setups for advanced
         use cases.
