Use conditional compilation to call swprintf() when building with clang instead of swprintf_s(), which depends on the Microsoft-specific __local_stdio_printf_options symbol that's not available with LLVM's linker.
This resolves the linker error:
ld.lld: error: undefined symbol: __local_stdio_printf_options
The change maintains compatibility with both MSVC (using swprintf_s) and clang (using standard swprintf) while preserving the same functionality.
resolves #101
