Deploy latest version to https://pypi.org/

[lexknuther]

As of trio 0.18.0, the hazmat package has been replaced with the lowlevel package. You already made this change in your code, you just need to upload a new version to pypi.

[marcolettieri]

latest version still 0.3.1!

[lexknuther]

I was asking you to bump the version. The one that's deployed on pypi doesn't work with the latest version of trio.

It'd be really helpful if you could make this release. trio-paho-mqtt is currently non-functional without this update.

Can you release the new version? with trio=0.19.0 I get an AttributeError when I want to receive messages.
