Iterates through namelist of archive, and retrieves the parent directories of each file as a set

Created test zipfile with zip -r -D ../demo_finder_noimplicit.zip *

Hi @tyler-c2s,
thanks a lot for implementing this. Here just a few minor corrections. Furthermore, do you know in which Python version this syntax was introduced:

def namelist_with_implicit_dirs(root: ZipFile) -> List[str]:

The pyproject.toml currently specifies requires-python = ">=3.0", which should be updated accordingly.

Great point. Typing was introduced in py 3.5. Happy to limit to that version, or as python <= 3.7 is now End Of Life we could limit the version to >=3.8

Great. Thanks. I have quickly changed it myself. Let's stay with 3.5 as minimum requirement.
