     * Cross-origin solution to communicate between tabs, windows, and iframes.
       Usage:
          - Create a new Teller instance.
            - If you want to use a custom message type, you can pass it to Teller<MyMessageType>.
            - const tellerManager = new Teller<MyMessageType>();
          - Call tellerManager.sendMessage({message, targetWindow, origin}) to send a message to the other tab/window/iframe.
          - Call tellerManager.setupListener({onReceiveMessage}) to listen for messages from the other tab/window/iframe.
          - Call tellerManager.close(); to close the active listener.
