Thanks! This library is very useful, and I’ll try to keep it in good shape. I've rebased this branch onto master (including #97, #98), and all tests are now green....

@jbschiratti Sorry, some previous commit hashes were changed when I rebased histories. I've not changed `examples/plot_feature_names_analysis.py` in this PR. The history was fixed and this PR changes only **.github/fowkflows/main.yml**, **setup.py**,...

#100 includes these ubuntu/python updates. Therefore, I close this PR.
