Now, the plugin works with css places inside `css` tag. However, css may often be stored near html

Example 1 (`html` tag):
```js
import {styles} from 'somewhere';

//...

html`
${styles}

.abc {
color: green;
}

...

....
`
```

Example 2 (`svg` tag):
```js
import {styles} from 'somewhere';

//...

svg`
${styles}

// ....


....
`
```

There are also some minor cases when some styles are inlined:
```js
html`

...

`
```

The proposal is to at least add support of first 2 major cases (Example 1, 2), however, would be nice to support all possible variants.
