I don't know much about TS so I need outside help on this one.

What's innerRef?

[RafalFilipek]

innerRef allows you to get reference to inner component.

const MyEmotionComponent   = styled('div')`color:red`;
let myRef;

<MyEmotionComponent  ref={(ref) => myRef = ref} /> // myRef - MyEmotionComponent 
<MyEmotionComponent  innerRef={(ref) => myRef = ref} /> //  myRef - div element

While we're talking abut extra props for components, there is also css prop.

I'm doing the TypeScript definitions for them now and I'll send a PR in a sec.
