Add WASM (Emscripten) compatibility

[TJKoury]

Add pragmas to account for the differences in compiling using the Emscripten pipeline.

`#include

#ifndef EMSCRIPTEN
#include
#endif

int main() {
std::cout << "Running on ";

#ifdef EMSCRIPTEN
std::cout << "Emscripten (WebAssembly)";
#else
std::cout << "Native platform";

// File system operations only if not Emscripten
std::ofstream file("example.txt");
if (file.is_open()) {
    file << "This is a test file.\n";
    file.close();
    std::cout << " - File system access available.";
} else {
    std::cout << " - Failed to write to file.";
}

#endif

std::cout << std::endl;
return 0;
