Question: Is there a simple way to get a type reduced to only primitives?

For example, if I have a type that is:
```
type Company = {
name: string
employees: Person[]
}

type Person = {
name: string
age: number
}
```

How can I get the deeply interpreted type, so that in Company instead of a reference to another type alias I get the properties of Person in there.

No file, test, or entry point is named. Start by checking ts-morph's type APIs and the TypeScript compiler's type model for recursively expanding aliases. Done means determining whether a supported API provides this result or documenting the limitation and required scope.
