to_string should add a \n to the end of the json

[Redhawk18]

Hey there! I'm here because I had a bug today that caused the server I was sending a the json to think I was sending a never ending message because I assume how that server parses jsons includes the new line as the end of the json.

For reference this is the code that didn't work

        stream
            .write_all(to_string(&self).unwrap()).as_bytes())
            .await;

And here's the code that did

        stream
            .write_all((to_string(&self).unwrap() + "\n").as_bytes())
            .await;

The JSON standard requires no such thing. It may be that the stream requires newline-terminated messages or similar.
