[Feature request] Add async commands support

[AldeRoberge]

Would it be possible to add a way to call async commands?

    [ConsoleMethod("/register", "Create a new user")]
    public static async Task Register(string email, string password)
    {
        await _authenticationController.Register(email, password);
    }

You should be able to execute this command. The only downside is this unnecessary log:

The workaround for this log is to create a wrapper function instead:

[ConsoleMethod("/register", "Create a new user")]
public static void RegisterUser(string email, string password)
{
    _ = Register(email, password);
}
