new release > 3.0.0

[zerwes]

The v3.0.0 release is more then outdated.
We released a script using the python binding (https://github.com/Rosa-Luxemburgstiftung-Berlin/jira2zammad) requiring the PR #254
So the easy way to install the dependencies via pip requirements is not working, as the current pip release is missing relevant features.
I know, pypi releases are often annoying, but a new release would reflect the latest changes of the lib (open source lives)
Thank you for your software, it helped us a lot!
