Support universal argument

[rirze]

Been using this package with great joy so far-- love the concept.

I was a bit surprised when I tried doing an universal argument (C-u -- 4) on parrot-rotate and it didn't work like I intuited it would. Is there a reason for this lack of behavior or can it be added as a feature with a pull request?

That's an interesting idea. I figured people would want to see the rotations and cycle through them, but I could see how jumping directly to the rotation you want could make sense.

I'm a bit strapped on time when it comes to implementing new things for parrot, but we'll see if I or someone else comes up a PR for this feature first.
