Create event with attendees

With version 7.x of iCalendar for Python Calendar and Event components can be created using the new() method. This ensure good defaults are set to be compatible with RFC 5545.

I had previously written about using the library before the new() method existed and this makes it much easier to build good calendars. I was contacted by Nicco, one of the repository owners, on Mastodon to help put together a tutorial using new(). I'm really glad to have been part of this, both Nicco and Steve set a high bar for documentation, and it's refreshing to see.
