I am looking for a convenient way to get the ASN of the client IP that is connecting to my service. 

While I can import a thrid party ip-to-asn database and query via hosted sql, there should be a way to include this minimal extra information in the provided [@vercel/geoloation](https://vercel.com/docs/functions/vercel-functions-package#geolocation) function to save on compute and network usage, limit dependencies, and simplify deployment.

### Current versus Expected behavior

```
import { geolocation } from '@vercel/functions';
 
export function GET(request) {
  const details = geolocation(request);
  return Response.json(details);
}
```
```
{
  "city": "New York",
  "country": "US",
  "flag": "🇺🇸",
  "countryRegion": "NY",
  "region": "dev1",
  "latitude": "40.7128",
  "longitude": "-74.0060"
+ "asn": "7922",
+ "as": "Comcast Cable Communications, LLC",
}
```

Has there been any update on this? It seems like the documentation for the function is unchanged.
