gallery.removeEventListener

[johtso]

There should probably be a removeEventListener function. Currently I have a listener that I only want to fire the first time the event happens (after the first image has loaded). It would be nice to be able to clean up after myself.

Instead of removeEventListener, I'd recommend exposing the underlying options as seen below. That gives the possibility to use once, or signal which is the superior way to remove an event listener nowadays.

- public addEventListener(name: [...], callback: [...]): void {
-     this.elementRef.addEventListener(name, callback);
+ public addEventListener(name: [...], callback: [...], options?: AddEventListenerOptions): void {
+     this.elementRef.addEventListener(name, callback, options);

@PowerKiKi even better! Thanks, I didn't know you could do all those things with options.
