Add the new websocket package (which is just a helper for kataras/neffos) and an example for go server, client, browser client and nodejs client. Add a .fossa.yml and the generated NOTICE file for 3rd-party libs. Update go.mod, go.sum. Update the vendor folder for pongo2 to its latest master as well

However, `neffos.(min.)js` is a NPM package too so alternatively,
you can use it as dependency on your package.json and all nodejs-npm tooling become available:
see the "browserify" example for more-->

var wsURL = scheme + "://" + document.location.hostname + port + "/echo";
var outputTxt = document.getElementById("output");

// If "await" and "async" are available, use them instead^, all modern browsers support those,
// all of the javascript examples will be written using async/await method instead of promise then/catch callbacks.

// addMessage("connected to namespace: " + msg.Namespace);
