[PostCSS] plugin to unwrap nested rules closer to Sass syntax.

```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;
}
```

  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 `^&`.
