title: react-cookie unable to set expires or maxAge
body: <p>I cannot seem to set the expiration for a cookie with react-cookie... here is my setup:</p>
  
  <pre><code>import { Cookies } from 'react-cookie'
  const cookies = new Cookies()
  import moment from 'moment'
  </code></pre>
  
  <p>The following attempts have failed:</p>
  
  <pre><code>cookies.set('cookieName', {key: value}, {path: '/', expires: new Date(Date.now()+2592000)})
  cookies.set('cookieName', {key: value}, {path: '/', expires: moment().add(30, "days")})
  cookies.set('cookieName', {key: value}, {path: '/', maxAge: 2592000})
  </code></pre>
