Including PIL image formats causes unnecessary bloat (was: Onefile size bloat)

🐛 Bug Description

Onefile size bloat in ver 4.1.1 - onefile exe size grew by 2MB

🖥️ Environment

1. Nuitka Version, Python Version, OS, and Platform

4.1.1 Commercial: None Python: 3.13.12 (tags/v3.13.12:1cbe481, Feb 3 2026, 18:22:25) [MSC v.1944 64 bit (AMD64)] Flavor: CPython Official GIL: yes Executable: C:\Program Files\Python313\python.exe OS: Windows Arch: x86_64 WindowsRelease: 10 Version C compiler: \AppData\Local\Nuitka\Nuitka\Cache\DOWNLO1\pip\private-6533d32b\Lib\site-packages\ziglang\zig.exe (zig.exe 0.16.0).

3. Nuitka Command Line Options

🚫 Unwelcome Practices (Please Read)

• No Screenshots of Text: Do not post screenshots of code, errors, or console output unless absolutely necessary (e.g., a GUI display problem). Provide text directly so it's searchable and copyable. Reports without proper text are likely to be rejected.
• Do Not Close Issues Yourself: We will close issues once they are resolved in a stable release. If you find your issue is invalid, you may close it, and we will tag it as invalid or even delete it later.
• Do Not Report Against factory Branch: Unless specifically asked, avoid reporting issues found on the factory branch as it's often unstable. Discuss on Discord first.
