Windows support

[Mersoltane]

1. amigo/init.py

• Added DLL directory paths for Windows to load required libraries (MKL, MS-MPI, OpenBLAS)
• Uses environment variables for flexibility (OPENBLAS_DLL_DIR, MSMPI_BIN)
• Now properly exports MemoryLocation enum from the compiled extension

2. amigo/model.py:

• Updated _build_module() to:
• Add venv Library path to CMAKE_PREFIX_PATH for MKL detection
• Pass BLAS/LAPACK library hints to CMake on Windows
• Pass MS-MPI include/library paths to CMake on Windows
• Generate CMakeLists.txt with C++17 standard and MSVC /permissive- flag

3. cmake/amigoAddModule.cmake:

• Fixed output directory for multi-config generators (Visual Studio)
• Now properly places .pyd files in the source directory instead of Release/Debug subdirectories

4. amigo/amigo.cpp (already existed, no changes needed):

• Already had MemoryLocation enum properly defined - just needed rebuilding

5. Updated the requirements.txt

[Mersoltane]

I actually found an efficient way to do instead:

• Instead of passing library paths from Python at build time, the main amigoConfig.cmake now properly exports BLAS/LAPACK/MPI settings that were found during installation.

• Module builds (amigoAddModule.cmake) inherit these cached paths automatically, eliminating redundant find_package() calls.

• Removed duplicate dependency declarations between requirements.txt and pyproject.toml.
