Add high-order component.

[srph]

What

• Adds a resize HOC as discussed in As HOC #1
• This adds a additional dependencies on omit and merge.

So far, I can't write any tests because:

• I think the API I just wrote sucks (but I think it matches the original API).
• The tests doesn't seem to be originally working:

Error: TypeError: 'undefined' is not a function (evaluating 'RegExp.prototype.test.bind(/^(data|aria)-[a-z_][a-z\d_.\-]*$/)')

Usage

import resize 'react-window-resize-listener/resize'; // lmao

@resize
class C extends Component {
  render() {
    console.log(this.props); // { windowWidth, windowHeight }
  }
}

I think we should put it in a property so we don't pollute the props, e.g., this.props.window.width.

No pressure! Thanks for your work ;). Feedback is welcome!
