Use gzip size on a non minified output

[samouss]

From the version 5.0.0 the gzip size is always computed on a minified bundle. But it might happen that you want to display the size for a non minified bundle (e.g Rollup is used to generate two bundles one minified and one non minified).

filesize({
  showMinifiedSize: false,
  showGzippedSize: true,
}),

// expected output → file size gzipped on non minified source code

---

filesize({
  showMinifiedSize: true,
  showGzippedSize: true,
}),

// expected output → file size gzipped on minified source code
