Access websocket on port not equal 80

[afr4283]

You might want to use
let gateway = ``ws://${window.location.host}/webserialws``;
instead of
let gateway = ``ws://${window.location.hostname + window.location.port + window.location.pathname}/webserialws``;

That combination of hostname, port and pathname is not working at all, even on port 80, it tries to access /webserial/webserialws

Thanks for the suggestion, but I don't have a test device at the moment, could you please do a PR to implement this feature?
