Bump version to 0.0.207

Fix __init__.py being private (#1556 )
Previously visibility::module_visibility() returned Private for any module name starting with an underscore, resulting in __init__.py being categorized as private, which in turn resulted in D104 (Missing docstring in public package) never being reported for __init__.py files.

 To add a test fixture, create a file under `resources/test/fixtures`, named to match the `CheckCode`
