title: how to customize DataEntryActivity for card.io
body: <p>is there a way to set the screenOrientation of io.card.payment.DataEntryActivity to be landscape? I tried to set it in Manifest but app crashed with error</p>
  
  <pre><code>             io.card.payment.DataEntryActivity requires attribute android:screenOrientation="portrait"
  </code></pre>
  
  <p>so, how could I customize this page? if I can't,  is there a way that just delete this page? I think only credit card number should be enough for me and I don't need the expiration  date.</p>
  
  <p>Thanks  </p>
