Customized scoped package ranking?

Is there a way to differentiate scoped packages from other 'external' packages? For example, I'd like to enforce scoped imports this way:

```js
// This is ok
import React from 'react'
import @org/package

...
// This should fail
import @org/package
import React from 'react'
```

Our company has internal scoped packages and we'd like to enforce the ordering of their imports as well. I'm happy to do the work if this functionality doesn't currently exist. I just wanted to make sure I can't already do this and you're open to adding a feature like this.

Review the plugin's existing import-ordering behavior and documentation first, then determine whether scoped packages can already be separated from other external imports. Define the configuration and ordering behavior needed for internal scopes, and add coverage showing both accepted and rejected import orders.
