🎉 Event Handling

/**
* Adds an event listener to the AudioPlayer instance
* - Accepts any HTMLAudioElement event and a handler function.
* - Returns index of handler function in this._eventHandlers[event] array. Can be passed to this.off to remove the listener.
*/
audio.on(event, handlerFunction);

/**
* Removes all listeners associated with an event from the AudioPlayer instance,
* or optionally a specific listener if handlerIndex is specified
* - Accepts the event name and optionally the index of a specific listener to remove.
*   If no handlerIndex is provided, removes all listeners bound to the event.
*/
audio.off(event, handlerIndex);
