Improving event listeners in ARnft class and other classes

[kalwalt]

@albjeremias I would collect here infos about this topic from discussion #208 #206 #189 To summarize it is possible to extends the ARnft class with the EventEmitter class:

export default class ARnft extends EventEmitter

see comment https://github.com/webarkit/ARnft/pull/208#issuecomment-936757805 linked article: https://javascript.plainenglish.io/how-we-can-use-node-js-event-emitter-5c9e39c38749

I found that there is also a typed package to help with the Typescript language tiny-typed-emitter read this stackoverflow article

I have opted for another solution: I created a target property inherited to the EventTarget (MDN ref: https://developer.mozilla.org/en-US/docs/Web/API/EventTarget) and the target is attached to the Window or Global object:

 private target: EventTarget;
 // In the constructor...
 this.target = window || global;
 // Then you can use your target as always...
 this.target.dispatchEvent(initEvent);

I will link the upcoming PR with more details.

We should make other improvements in this field. We should create an Event base class and then extends to an DataEvent class, so we can do:

this.target.dispatchEvent(new DataEvent(ARnftEvent.ARNFT_DISPLAY_EVENT, data));

where ARnftEvent.ARNFT_DISPLAY_EVENT = 'Display_event'

data = { message: "hello" } but is injected in {detail: data} without to wite this part. Note this is a pseudo code! I will elaborate this idea in the issue when i have time.
