Subject: [PATCH] added another example.

Added Router, request, close listener, and sec-websocket-key examples. All of these may be important when developing a real-world application for:
1. Identifying the socket connection of the client
2. Keeping an up-to-date list of connected sockets.

+To reach request object and disconnect event: 
+```dart
+  import 'package:shelf_router/shelf_router.dart';
+
+  var app = Router();
+  app.get("/ws", FutureOr<Response> handler(Request request) {
+   return webSocketHandler((WebSocketChannel webSocket) {
+      // now we have access to request argument
+
+      // that key is being generated by the websocket itself, every connection has a unique key.
+      final webSocketKey = request.headers["sec-websocket-key"];
+
+      webSocket.stream.listen((message) {
+        webSocket.sink.add("echo $message");

+    })(request);
+  });
+  await io.serve(app, 'localhost', 8080);
