[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;
}
`
