Add support for font sub styles

Instead of only allowing using the font name, passing the style would be nice

Example:

Lato:wght@100

fetch it from the url

```
<link rel="preconnect" href="https://fonts.gstatic.com">
<link href="https://fonts.googleapis.com/css2?family=Lato:wght@100&display=swap" rel="stylesheet">
```
