Inline critical-path css and load the existing stylesheets asynchronously.
Existing link tags will also be wrapped in ```<noscript>``` so the users with javscript disabled will see the site rendered normally.

## inline(html, styles, options?)

- `html` is the HTML you want to use to inline your critical styles, or any other styles
- `styles` are the styles you're looking to inline
- `options` is an optional configuration object
  - `minify` will minify the styles before inlining
  - `extract` will remove the inlined styles from any stylesheets referenced in the HTML
  - `basePath` will be used when extracting styles to find the files references by `href` attributes
  - `ignore` ignore matching stylesheets when inlining.
