[DRAFT] Angular 14

[majora2007]

I have converted the library to Angular 14 which required strict typing. I have updated all but 2 lines, as those change logic flow. I'm open to any pointers on how to close those out.

Line 1:

protected debounce(func: Function, wait: number): Function {
    const throttled = this.throttleTrailing(func, wait);
    const result = function () {
      throttled['cancel']();
      throttled.apply(this, arguments); // this doesn't have a type and arguments isn't seen as []. I tried casting and using same type as throttleTrailing, but no luck
    };
    result['cancel'] = function () {
      throttled['cancel']();
    };

    return result;
  }

Line 2:

protected getScrollElement():  HTMLElement {
    return this.parentScroll instanceof Window ? (document.scrollingElement || document.documentElement || document.body) : (this.parentScroll || this.element.nativeElement);
  }

The problem is that document.scrollingElement is an Element type, while all others are HTMLElement. But in the code, we actually use properties only on HTMLElement and not Element.

If I could get any support on this, we can get Angular 14 out of the way and migrate up to 15 as well.

I ended up fixing throttled.apply(this, arguments); and removed one of the Elements for getScrollingBlock().

Trying to get the code running, but the demo doesn't see virtual scroller for some reason.

@iharbeck any chance you could review this and give me some suggestions on how to properly test this out?
