Add CLI help and version flags

[vincere-mori]

Fixes #27

Adds early handling for --help\ and --version\ before the GUI starts. The version output uses \DMRCRACK_VERSION\ from \include/version.h.

Validation:

• \git diff --check\

I could not run the Windows/CUDA build locally because this machine does not have the Visual Studio/CUDA toolchain required by \�uild.bat.

Thanks for the PR!

One thing to fix before it can build: <shellapi.h> needs <windows.h> to be included first. It uses types like LPWSTR, HRESULT, and DECLARE_HANDLE that aren't defined yet at that point. Move <windows.h> to the top:

#include <windows.h>
#include <shellapi.h>
#include <stdio.h>
#include <wchar.h>
