Issue description:

I'm trying to install python-ldap on Windows in a Conda environment, using the prebuilt wheels available at https://github.com/cgohlke/python-ldap-build?tab=readme-ov-file. pip fails with the following error:

$ pip install /c/temp/python_ldap-3.4.4-cp311-cp311-win_amd64.whl
Processing c:\temp\python_ldap-3.4.4-cp311-cp311-win_amd64.whl
ERROR: Wheel 'python-ldap' located at C:\temp\python_ldap-3.4.4-cp311-cp311-win_amd64.whl is invalid.

I tried several version of Python (using the appropriate wheel) for version 3.4.3 and 3.4.4.

I also attempted to install the module with python install python-ldap after installing the MSVC tools but it also fails saying lber.h is not found.

For the record, I have been using successfully the pre-built version for a long time with Python 3.9, installed from the former location maintained by C. Gohlke (https://www.lfd.uci.edu/~gohlke/pythonlibs/#python-ldap).

Steps to reproduce:

1. Create a Conda environment with the Python version you want: conda -n testldap python=3.11
2. Download the amd64 version matching the Python version
3. pip install /path/to/downloaded/wheel

Operating system:

Windows 11

Python version:

Tested with 3.9 to 3.11

python-ldap version:

3.4.3 and 3.4.4
