`reverseInnerCoordinates` is not exported

Docs mention you can use `reverseInnerCoordinates` but it is not exported.
```js
import { reverseInnerCoordinates } from 'content-tag-utils';
      // ^ Module '"content-tag-utils"' has no exported member 'reverseInnerCoordinates'.
```

The example in the docs doesn't make clear what `extractTemplates` does.
