Fixes issue with WKWebView when loading an HTML file from the app's bundle
Due to a bug in WKWebView, check this StackOverflow question, local HTML files could not be loaded from the application's bundle. Because WLXWebViewReloader uses an internal web view to load the client version of socket.io in order to connect with the watcher server, a simple HTML page was needed to load the library and establish the connection. In this new version that HTML page is actually served by the webview-reloader-server so loading the HTML from the application's bundle is no longer an issue.
