Magic.py "wrong type" error on Windows 10

[GeneralBison]

OS: Windows 10 22H2 (19045) Python Version: 3.11.0

First of all thank you massively for developing this solution, I started getting really suspicious of the original Gamma launcher after finding out it was heavily obfuscated on top of the "Disable AV and run as admin" stuff.

Every time gamma-launcher needs to extract an archive, it throws a TypeError. I've tried both the pre-packaged executable and my own venv (with Python 3.11). I've tried to investigate the issue myself but have had issues setting up a debugging environment and catching the exception, will keep trying.

Let me know if there's any additional information I could provide or tests I could perform.

(env) PS D:\Games\gamma-launcher> gamma-launcher gamma-setup --gamma .\GAMMA\

Hey ! No idea of what is happening, it seems to be an error in magic module.

To be fair, I was focusing on Linux dev .... Not sure if Windows is fully supported. I've made a quick branch to solve your issue .. Can you give it a test ? (expect more errors)

[GeneralBison]

The fix worked, I'll test more tomorrow with a full install. I tried v1.5 as a workaround and ran into other errors with mod downloading, I'll make a separate issue when I get around to reinstalling.

full-install tested on Linux without magic module, everything went fine.

@GeneralBison did you have to check Win32 install ? No more errors ?
