Does stylecleanup support imported styles ?

We try stylecleanup on our codebase and it didn't find any unused styles.

We were wondering if stylecleanup is supposed to delete grayText in the example below.

```
// styles.js
import StyleSheet from 'react-native';

export default StyleSheet.create({
grayText: {
color: '#D0D0D0',
},
redText: {
color: '#FF0000'
},
});
```

```
// component.js
{...}
import styles from './styles.js';

class Example extends Component {
render({

Error: ...

});
}
```

Start with the styles.js and component.js examples in the issue and run stylecleanup against them. Trace how the tool resolves the imported styles object, then verify that grayText is identified as unused while redText is retained.
