support for clsx?

Hey, thanks for this plugin :) Works great in most cases but it would be nice to support classes added with `clsx`

I have an example component like this:

```

The first argument for clsx would trigger a lint warning if it was added directly to `className=""` but it doesn't work here.
I tried adding a config like for the tailwind config, like:

```
"unocss/classnames-order": [
1,
{
"callees": ["clsx"]
}
]
```

But it didn't have any effect

No files or tests are named in the issue. Start by locating the className handling and the existing tailwind-config callees option, then reproduce the provided clsx example. Done means classes in clsx calls are checked and the shown configuration enables that behavior.
