hexo-image-sizes uses the router now

I noticed your plugin this weekend and it taught me how to use the Hexo router! I just wanted to drop a note saying that hexo-image-sizes uses the router now as well, and so should work with the other asset pipeline plugins.

Hey @ottobonn, that's amazing. I will take a look and update the readme then
