wording

Hey,

I think it should say something like minified + gzip in the output table, because it wasn't clear to me that this module also gzips the input. I though it only looks at minification. :)

Added a note to the readme and updated the output table. I kept the keys the same if it's used programmatically so that it wouldnt require a major version bump.
