Angular 9 Support

[Liioooo]

Angular 9 will be released in the near future and I would like to continue using your package.
Would be nice if it was compatible with ng9.

Agreed. Just updated an app to Angular 9 and get either ...

ERROR TypeError: Cannot read property 'nativeElement' of undefined
    at SlideshowComponent.push../node_modules/ng-simple-slideshow/__ivy_ngcc__/ng-simple-slideshow.es5.js.SlideshowComponent.setStyles

...or...

ERROR TypeError: Cannot read property 'nativeElement' of undefined
    at PointerService.push../node_modules/ng-simple-slideshow/__ivy_ngcc__/ng-simple-slideshow.es5.js.PointerService.bind

...Looks like code is being executed before the element has been instantiated by the renderer, so it can't get a reference to nativeElement.

[Last edit]
The simple fix I found was to move the code in SlideshowComponent from ngOnInit to ngAfterViewInit. At that point, the container ViewChild has a value, so the bind function in PointerService doesn't throw errors.

That's just what I did in my PR #102.
