Pusher WebSocket ISO

EXPERIMENTAL isomorphic WebSocket client for Pusher (pub/sub). Version 0.2.0. Supports browser, Node.js, React Native, and Web Workers. Unlike the official pusher-js library, this package removes DOM dependency, JSONp authorization, and SockJS fallback for cross-environment compatibility. Uses XHR fallbacks built into the same file. Not suitable for production; use the official pusher-js for critical applications.
