Switched to Arian's Mii renderer, also added another Mii easter egg 👀

TODO:

Then factor the "body_"/"portrait_" prefix separately.

To make up for the lack of transparency, you could just use a static background color, if, in your app, Mii images are always displayed against one background color. If not, maybe you can concede and make the background color the Mii's favorite color or something like that, and failing all that... just go with PNG.
