Please explain the detail here:
This pull request fixes an ELF parser size bug, which was causing some test_elf_*.py tests to fail. It does so by using implementation-independent integer types in BunkaiPrimitive. And also reverts the test_elf_*.py tests for Windows.

The root cause of this issue is the difference in the sizeof types like long across different platforms:

On x64 Windows 11:

Python 3.12.2 (tags/v3.12.2:6abddd9, Feb  6 2024, 21:26:36) [MSC v.1937 64 bit (AMD64)] on win32

On x64 Ubuntu:

Python 3.10.12 (main, Nov 20 2023, 15:14:05) [GCC 11.4.0] on linux

What have you done so far?

Tell me what you've tested to assure your change is right.

• All tests passed on your machine (python -m unittest)
• Added test cases for new feature
• Nothing / Test not required

(It's not mandatory to check even one of them, but test cases make it easy for the author to review your PR.)
