     * Creates an Observable by using the `addHandler` and `removeHandler`
     * functions to add and remove the handlers, with an optional selector
     * function to project the event arguments to a result. The `addHandler` is
     * called when the output Observable is subscribed, and `removeHandler` is
     * called when the Subscription is unsubscribed.

     * @param {function(handler: Function): any} addHandler A function that takes
     * a `handler` function as argument and attaches it somehow to the actual
     * source of events.
     * @param {function(handler: Function, signal?: any): void} [removeHandler] An optional function that
     * takes a `handler` function as argument and removes it in case it was
     * previously attached using `addHandler`. if addHandler returns signal to teardown when remove,
     * removeHandler function will forward it.
     * @param {function(...args: any): T} [selector] An optional function to
     * post-process results. It takes the arguments from the event handler and
     * should return a single value.
