title: PhpWord roman numeral for page number
body: <p>I'm using this phpword library: <a href="https://github.com/PHPOffice/PHPWord" rel="nofollow noreferrer">https://github.com/PHPOffice/PHPWord</a></p>
  
  <p>And I have a trouble about roman numeral in page number, Is it possible for phpword to show page number in roman numeral instead of standard numeral?</p>
  
  <p>i found this line of code in the library:</p>
  
  <pre><code>protected $fieldsArray = array(
          'PAGE' =&gt; array(
             'properties' =&gt; array(
                 'format' =&gt; array('Arabic', 'ArabicDash', 'alphabetic', 'ALPHABETIC', 'roman', 'ROMAN'),
             ),
             'options' =&gt; array('PreserveFormat'),
          ),
  ...
  );
  </code></pre>
  
  <p>just wonder how i can get it.</p>
