Related to python-attrs/attrs#1265

One straightforward fix is to just copy-paste the code into magic-wormhole codebase. A slightly better way might be to integrate into a "public" place in Twisted and use that .. I would approve either kind of PR :) but the first one is easy and doesn't need co-ordinated releases

Ah, this is already fixed in 947bb85 ... it is in release 0.15.0 from earlier this month: https://pypi.org/project/magic-wormhole/0.15.0/
