* Fix context reuse test
* Don't update files with at-apply when content changes
* Prevent at-apply directives from creating new contexts
* Rework apply to use local postcss root
We were storing user CSS in the context so we could use it with apply. The problem is that this CSS does not get updated on save unless it has a tailwind directive in it resulting in stale apply caches. This could result in either stale generation or errors about missing classes.
* Don’t build local cache unless `@apply` is used
* Update changelog
* Replace chalk with picocolors
Already used in latest postcss, autoprefixer and browserslist versions.

* Update `dim` function

* 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
* Prevent nesting plugin from breaking other plugins
This uses a private API but it’s the only solution we have right now. It’s guarded to hopefully be less breaking if the API disappears.
* Update changelog
This would be better as a symbol but the stringy-ness of class candidates is fairly well baked into assumptions across the codebase. Using `new String` with a well placed check seems to solve the problem.
* 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`
* Add failing tests for negative utility detection
We're not generating them properly in all cases, when using at-apply we sometimes crash, and safelisting doesn't currently work as expected.
* Refactor
* Generate utilities for negatives before and after the prefix
* Properly detect negative utilities with prefixes in the safelist
* Refactor test a bit
* Add class list tests
* Update changelog
