IRC integration

[haansn08]

I have been following the guide at https://coq.zulipchat.com/integrations/doc/irc. After starting the bot like below and sending an IRC message, this exception occurred. No messages are relayed in either direction.

$ python irc-mirror.py --irc-server=irc.libera.chat --channel="#coq" --nick-prefix=irc_mirror --stream="#coq on irc.libera.chat" --site="https://coq.zulipchat.com" --user="irc-bot@coq.zulipchat.com" --api-key="xxxxxxxxx"

Listening now. Please send an IRC message to verify operation

I don't have access to a live bridge to test, but @asdf8dfafjk can you test if simply bumping the irc version works?
