Parsedown library missing

An absolute hack fix is to copy Parsedown.php into google-calendar-events/includes/events and edit event-builder.php to first fix the typo ‘\’ on line 678, and then add this at the top of the file:

use SimpleCalendar\Abstracts\Calendar;
require("Parsedown.php");
use Parsedown;

@jrendell can you please verify if https://github.com/Xtendify/Simple-Calendar/releases/download/3.1.38.1/simple-calendar-3.1.38.1.zip works for you??If yes, I will release this on w.org.
