Description of the false positive

Within the project module cogent3.util.io, importing from the standard library io is incorrectly labelled as a cyclic import.

Thanks for reporting. I think you're right. The analysis seems to confuse the cogent3.util.io and the io library.

This issue also affects mypy, where it probably confuses mypy.types with stdlib types, see example (note there are also some legitimate errors in that and other files, but errors related to imports from typing, enums etc are all false positives).
