Typescript and non-Babel environments example out of sync with TypeScript definitions

The `universal` options in the [example](https://github.com/faceyspacey/babel-plugin-universal-import#typescript-and-non-babel-environments) (`chunkName` and `resolve`) don't exist in the current [react-universal-component declaration file](https://github.com/faceyspacey/react-universal-component/blob/master/index.d.ts). Interestingly, the [Flow types](https://github.com/faceyspacey/react-universal-component/blob/master/src/flowTypes.js#L43-L61) contain the properties, though.

Can this example be updated with the appropriate options that should be passed when used in a TypeScript project or can the TypeScript definitions for react-universal-component be updated to reflect the valid options?
