`CliLocalSession` waits for keypress when exiting

Hi @marcogmaia ,

first of all, thank you very much for using this library.

I tried your code in the following environment:

• visual studio 2022, Debug build
• visual studio 2022, Release build
• linux kubuntu, GCC v. 11.4.0

In all three cases, I've got the expected output:

c:\Progetti\github\esempi_cli\cli_example\x64\Release>cli_example.exe
cli> exit
Stopping scheduler...
Waiting for extra keypress...
Exiting from main.
c:\Progetti\github\esempi_cli\cli_example\x64\Release>

(no extra keypress needed, by the way: I've just entered "exit" followed by key).

The complete code is:

#include <cli/loopscheduler.h>
#include "cli/clilocalsession.h"
#include "cli/cli.h"

int main() {
    std::atexit([]() { std::cout << "Exiting from main."; });

    auto cli = cli::Cli(std::make_unique<cli::Menu>("cli"));
    cli.ExitAction([](auto& out) { out << "Waiting for extra keypress...\n"; });

    auto scheduler = cli::LoopScheduler();
    auto session = cli::CliLocalSession(cli, scheduler, std::cout, 400);
    session.ExitAction([&scheduler](auto& out) {
        scheduler.Stop();
        out << "Stopping scheduler...\n";
    });

    scheduler.Run();

    return 0;
}

using C++20 standard and the latest version of cli library (i.e., v. 2.1).

Please, let me know what differs from your environment.

@daniele77, thanks man. I'll test with your configs when I get the time. I compiled with clang on windows.

It seems to correctly work with PowerShell, the issue that I was experiencing was with some integrated terminals, like the VSCode integrated terminal and Windows terminal, but if the application is used in a standalone mode it works correctly.
I've tested with msvc2022 and clang17.
