Add badges component

[guastallaigor]

Is your feature request related to a problem? Please describe.
Add a badges component kind of like github has but 8bit-like

Describe the solution you'd like

First draft

Describe alternatives you've considered
Not adding this or changing it to other classes like closable (with an close icon) or other things

Additional context
Up to this moment the badges must have two sides, a first and black one and the other one changes color. Suggestions are welcome.

Second draft, added hability to change left/right side

Sounds great 👍

We might like to use a simple badge like the image below. 🤔

Could you do something like the following? 🤔
Or should I have a different style from this Issue?

<span class="nes-badge">10</span>

<!-- class name and elements are provisional -->
<span class="nes-badge is-splited is-primary">
  <label>npm</label>
  <span>1.0.0</span>
</span>

I like the idea and they look good. However I'm curious about where someone might use a two toned badge like this outside of the badges in say a Github README. Where else might it be used?

Regardless I think this could also be a good starting point/inspiration for button group or radio group.

@BcRikko I was thinking more like this badges:

But maybe I can try add a different approach like you've suggested.

@jjspace I'm not sure where exactly, that depends on the user. To me, I was planning on using this in the docs implementation that we were planning to create #180 , and a different private website I was starting to make.

I got the idea from Bulma. This implementation right now is just like github badges, but like Bulma, I was aiming for different implementations in the future.

I see. I'm still not sure where I'd use two tone badges like this but just because I don't have a use doesn't mean they're not useful 😄 They still look good and I do like the idea of fully fleshed out tags like Bulma has. I can definitely see a use for single tone tags or tags with a two tone X button and this is definitely a good start on that.
