A few housekeeping tasks:

• Cleaned some dead code and imports.
• Modified not( ... in ....) patterns to ... not in ... to be PEP compliant.
• Moved source into src to be uv compliant
• Added pyproject.toml to allow easier package and dependency management (e.g. through uv or poetry). The lower bound on the versions were set by identifying the earliest versions that passed the existing tests.

Feel free to comment or ask for modifications.
