Future3 | zmq not installed in Github action pytest environment

[votti]

Bug

What I did

I wrote a unittest for a new feature

What happened

Inoticed that the github action workflow was failing due to a missing zmq installation as zmq is currently not installed as part of the testing workflow: https://github.com/MiczFlor/RPi-Jukebox-RFID/blob/future3/develop/.github/workflows/pythonpackage_future3.yml

I expected this to happen

zmq should be also present in the github action workflow python environment used to run tests.

Further information that might help

A workaround that worked for me was to use unitest.mock to avoid importing zmq for my tests:

I tend to the conclusion that it's ok to mock zmq for unit tests (as long as zmq is not directly used in the tests).
