[PostCSS] plugin to unwrap nested rules like how Sass does it.

```css
.phone {
    &_title {
        width: 500px;
        @media (max-width: 500px) {
            width: auto;
        }
        body.is_dark & {
            color: white;
        }
    }
    img {
        display: block;
    }
}

.title {
  font-size: var(--font);

  @at-root html {
      --font: 16px
  }
}
```

will be processed to:

```css
.phone_title {
    width: 500px;
}
@media (max-width: 500px) {
    .phone_title {
        width: auto;
    }
}
body.is_dark .phone_title {
    color: white;
}
.phone img {
    display: block;
}

.title {
  font-size: var(--font);
}
html {
  --font: 16px
}
```

Related plugins:

* Use [`postcss-atroot`] for `@at-root` at-rule to move nested child
  to the CSS root.
* Use [`postcss-current-selector`] **after** this plugin if you want
  to use current selector in properties or variables values.
* Use [`postcss-nested-ancestors`] **before** this plugin if you want
  to reference any ancestor element directly in your selectors with `^&`.

Alternatives:

* See also [`postcss-nesting`], which implements [CSSWG draft]
  (requires the `&` and introduces `@nest`).
* [`postcss-nested-props`] for nested properties like `font-size`.
