Running Experiments BPM-2022 - pix framework dependency not found

Greetings, 
running the demo experiment of bpm22_experiments_script.py is not possible since the reference "pix_framework" cannot be resolved. 
Possibly this is due to the dependency in pyproject.toml, which is named "pix-framework".
Moreover, "requirements.txt" is nowhere to be found in the codebase.

Best,

Alan
