Use Tailwind's context.getClassOrder(classes) (#57)

* prefer Tailwind's `context.getClassOrder()` if it exists

We have to keep the existing code for now, since the plugin will prefer
the user's tailwind version. Hopefully we can remove this in future
versions.

* bump tailwindcss dependency

* add full getClassOrder polyfill

This will also add the `group` and `peer` for older versions of Tailwind
CSS

* Update `getClassOrder` polyfill to support all Tailwind v3 releases

* Add "parasite utilities" test
