* Preserve source maps for `@apply`
* Overwrite the source for all cloned descendants
* Preserve source maps when expanding defaults
* Verify that source maps are correctly generated
* Update changelog
* Temporarily move postcss to dependencies
This is unfortunate but upgrading postcss-js caused postcss to not be installed at all. This is fine except in this case of NPM <= 6 when running npx tailwindcss init, or yarn v1, or npm 7/8 with legacy peer deps behavior and doing a similar thing. Deduping will still allow the user to install postcss and upgrade it and Tailwind CSS will pick it up. A more permanent solution may involve hijacking require or something similar.
* Update changelog
* add prettier-plugin-tailwindcss
This will use the prettier plugin in our tests as well, yay consistency!
* ensure that both `group` and `peer` can't be used in `@apply`
This was only configured for `group`
* expose `sortClassList` on the context
This function will be used by the `prettier-plugin-tailwindcss` plugin,
this way the sorting happens within Tailwind CSS itself adn the
`prettier-plugin-tailwindcss` plugin doesn't have to use internal /
private APIs.
The signature looks like this:
```ts
function sortClassList(classes: string[]): string[]
```
E.g.:
```js
let sortedClasses = context.sortClassList(['p-1', 'm-1', 'container'])
```
* update changelog
* add sort test for utilities with the important modifier e.g.: `!p-4`
