Include dependency specifications in `pyproject.toml` format

[Auguste Baum]

Hi,

Thanks very much for providing the code to your paper, it is very informative!
Unfortunately, I am having trouble running the code. This is because it has been some time since this code has been written, and it is now difficult to see which versions of each dependency you used. Specifying them in the right format will allow the project to be much easier to run, hence more reproducible.

Would you happen to have the versions at hand? If you used an isolated environment system, such as conda, it could be as easy as running

conda env export -n <name_of_env>

Thanks for your attention and thanks again for publishing the project.
