irccat doesn't work (relies on outdated code)

[Johannes Sasongko]

This is mentioned in #142 (comment), but I don't think there was a proper bug report for it.

$ python3 -m pydle.utils.irccat chat.freenode.net

Thanks for the formal report.
Yes, it looks like irccat is woefully out of date, I may have overlooked it during the asyncio /py3.7 upgrade. Presently investigating a fix.
