Matrix chat for icalendar

[niccokunzmann]

We have opened a Matrix community space for chatting. We are already using it to coordinate work. There is a chat room dedicated to icalendar.

I invite you to join #pycal:chat.pycal.org on Matrix

@angatha and other contributors, you might be interested.
