C++20 Single Header Debugger Detection

The original project (XAntiDebug) has been rewritten in C++20Project address: https://github.com/Brassinolide/XAntiDebugExample code:

#include <iostream>
import xantidbg;
const XAntiDebug antidbg_global_instance([]() {    std::cout << "Debugger detected (global class)" << std::endl;    system("pause");    terminateself_nullptr();});
int main() {    antidbg_global_instance.sentinel();
    XAntiDebug antidbg;
    antidbg_global_instance.sentinel();
    if (antidbg.check_debug()) {        std::cout << "Debugger detected (temporary class)" << std::endl;        system("pause");        terminateself_nullptr();    }
    antidbg_global_instance.sentinel();}

Alternatively, more aggressively, use `bsod()` to blue screen the cracker’s computer (a blue screen is sufficient; it is not recommended to directly wipe the disk)

if (antidbg.check_debug()) {    bsod();}

It is actually not a single header file, as there is another SSE hardware-accelerated CRC32C implementation. Moreover, calling it a header file is inaccurate; it should be referred to as a module.
