License statement

[Fabian Affolter]

Currently there is no license statement. Could you please add a LICENSE file that contains the license text or add details to pyproject.toml?

For Nixpkgs shell-genie is marked as unfree for now but a clarification about the license would be much appreciated.

Thanks.

Hey @fabaff, I just added the license (MIT). Let me know if this fixes the issue.

Thank you.
