cljsExports with dots

How should I write a cljsExports line for a react-native package that contains a "/"?

For example, I'd like to use the library `'@react-native-community/art'` and require it from clojurescript with:

```
(ns my-rn-app
(:require [react-native-community.art :as art]))
```

I tried editing index.js to add:

```
cljsExports['react-native-community.art'] = require('@react-native-community/art');
```

and:

```
cljsExports['react-native-community'] = {};
cljsExports['react-native-community']['art'] = require('@react-native-community/art');
```

But neither of these seemed to work.

What do I need to add to `cljsExports` to get this to work?

Start with index.js and the existing cljsExports entries, then trace how the React Native bridge resolves names containing dots and slashes. Reproduce the @react-native-community/art require with the shown namespace and verify that the resulting ClojureScript import works without manual edits outside the expected export configuration.
