title: aiohttp with browser_cookie3
body: <p>I'm trying to use 'aiohttp' with 'browser-cookie3' however it doesn't accept the cookiejar, it shows the following message: "cannot unpack non-iterable Cookie object"</p>
  
  <p>My cookie works with 'requests' but isn't working with aiohttp</p>
  
  <p>How should I modify the Cookie object to make it work with aiohttp?</p>
  
  <pre class="lang-py prettyprint-override"><code>#browser_cookie3:
  cj = browser_cookie3.load()
  
  #iohttp error command:
  async with ClientSession(cookies=cj) as session:
  
  #Error message: "cannot unpack non-iterable Cookie object"
  </code></pre>
  
  <p>Note: I tried to use cj._cookies but didn't work too, no error message but couldn't Sign In.</p>
