Replace requirements.txt with pyproject toml

[whotwagner]

We need to prepare the aminer for the next debian release. The maintainer can easily create a debian-packet when we have a proper pyproject.toml. We already have one for vulture. We need to extend that pyproject.toml in order to have all the meta-data(authors, license etc...), all required dependencies(really all, even if they are installed with ansible) and for the executable-stub. We already use pyproject.toml in https://github.com/ait-testbed/attackmate/blob/main/pyproject.toml if an example is needed.

@whotwagner do you need this to be done now or can I do it in January?

[whotwagner]

January is okay
