With this commit, the game now supports SSL connections. In addition, the argument parsing workflow was fundamentally improved to provide a clearer, better-structured usage of command line arguments for different functionalities. It also includes updates to the help documentations - now, each of these functionalities are accessible as subcommands with their own help messages. A minor update was also made to the test suite to reflect these changes.

Moved the creation of argparse.ArgumentParser objects used to parse command line arguments into a separate module, `argument_parser.py`. This includes organizing all the add_argument calls into specific functions within this new module, in order to increase code readability, reusability and organization within the argument parsing codebase. All existing usages have been updated accordingly.
