RFC: Carousel about spartan

[theo-matzavinos]

I took a stab at this since it seemed pretty straightforward. The API I went with looks like this:

   <hlm-carousel orientation="horizontal" [plugins]="emblaPlugins">
      <hlm-carousel-content>
        <hlm-carousel-item>...</hlm-carousel-item>
        <hlm-carousel-item>...</hlm-carousel-item>
      </hlm-carousel-content>
      <button hlm-carousel-previous></button>
      <button hlm-carousel-next></button>
    </hlm-carousel>

Let me know if this is the direction you had in mind and if I should open a PR.

We will wrap around the official Angular wrapper: davidjerleke/embla-carousel#627

This is now possible with the following official Angular wrapper: https://github.com/donaldxdonald/embla-carousel-angular

looks awesome! One thing I'd might change is the directives for the buttons to become: hlmCarouselPrevious and hlmCarouselNext. Looking forward to your PR @theo-matzavinos
