   After installing python -m pip install types-cffi --user (1.15.1.15) I got this file structure in site-packages:

   where cffi-stubs/api.pyi has the right signature and _cffi_backend-stubs/__init__.pyi has the wrong one: def string(self, cdata: CData, maxlen: int) -> bytes | str: ... What is going on?
