Update getting-started.md (#175)

Add __name__ == "__main__" clauses and a make_app function so that the app can be run with the CLI too.

 > We can have multiple routes for WebSockets, but in this example we just get one for anything we need, adding an option of compression using SHARED_COMPRESSOR, max_payload_length of 1mb and an idle timeout of 12s just to show some most commonly used features you can see all these options in the [API Reference](api.md)
