you can now provide interview questions in your package.json

Instead of basic default values, you can now provide interview questions in your package.json:

```json
    "args": {
      "--kitten": "cute",
      "--dog": {
        "default": "also-cute",
        "description": "what do you think of dogs?"
      },
      "--frontdoor-url": {
        "default": "google.com",
        "description": "pork chop sandwiches"
      }
    }
```
