Expand support for other fields

I’ve tried parsing an atom field with this plugin & it failed. When I looked at the code there were no support for pubDate & category fields.
(Also in my dev environment I got an error on $content variable which was not set to empty string. Adding $content = ''; before foreach solved the issue.)

Here’s what I’ve added to the FetchFeedPageable_call function to extend the support. If you could incorporate these in future plugin revisions that would be great.

case "pubDate":
                $date=$item->get_date();
                $content .= '<div class="ItemDate">'. esc_html($date) .'</div>';
                break;

and

case "category":
                $category = $item->get_category();
                $content .= '<div class="ItemCategory">'.$category->get_label() .'</div>';
          	}

I would also recommend removing the hard
from the results, it’s best practices and folks can add the spacing/separators they need via CSS.

Hope this helps.
