pyproject.toml has no project section and breaks installation with pip

[ogarcia]

There is a problem with the pyproject.toml file, it does not have the [project] section declared and therefore the dependencies section is missing inside it. This causes that when a project that also uses pyproject.toml indicates that it has this project as a dependency, its dependencies (the python-pam dependencies) are not installed.

Something similar to this should be specified in pyproject.toml:

[project]
dependencies = [
  "six",
  "toml"
]
