Fix the build and other improvements

[tritao]

Hey,

First of all thanks for all the work on this. Just recently got exploring the code and what's there seems really cool.

But realized that some stuff seems broken out-of-the-box, which I've tried to fix it and make it work best to my knowledge.

CI also seems broken for the last few months, which makes me question, are you planning to keep maintaining this package? Need any help?
