Renamed `move_dist` attribute to `player_speed_units_per_seconds` in player configuration. Also implemented `__post_init__` method in Action class to handle conversion from str to Enum type. Added a utility function `custom_asdict_factory` to handle Enum serialization for actions. Various code updates are made to accommodate these changes. Fixes merge bugs.

A new command line interface has been added to Overcooked Simulator, which starts up the overcooked game engine server and a PyGame 2D Visualization window each in their own process. This is done using argparse for handling command line arguments. Furthermore, some minor changes have been introduced in the game server and GUI scripts to better handle processes and accept host and port arguments.

Removed the unused 'get_state_simple_json' method, added missing docstrings providing detailed explanations for functions in 'overcooked_simulator/game_server.py' and 'overcooked_simulator/simulation_runner.py'. Implemented a type hinting dictionary in 'overcooked_simulator/server_results.py'. These changes are aimed at improving code readability and maintenance.

The player id type is updated from 'int | str' to 'str' across different files to maintain code uniformity and avoid type-related errors. Removed the global constants (USE_PLAYER_COOK_SPRITES, SHOW_INTERACTION_RANGE, SHOW_COUNTER_CENTERS) from gui files for better code structure. Moreover, function annotations are improved by providing more specific types which helps in understanding the codebase. The diff adds additional details in the form of questions or short descriptions in the comments as well.

The update introduces a new function `get_json_state()` in overcooked_environment.py that exports the current game state in JSON format. Changes were made to player.py, counters.py, and game_items.py to include an additional `to_dict()` function which represents their current status as a dictionary. This commit also includes minor naming changes, such as renaming `beginning_time` to `start_time`.

The server (game_server.py) and client communication (overcooked_gui.py) now uses the WebSocket communication protocol. In setup.py, the 'requests' module was added as a new requirement. The game simulator now waits for a player to be ready before starting, stops a game environment if no step is taken within a minute, and pauses or unpauses a game environment. Player actions are now handled based on a new 'Action' type. The server also now handles several client types that can send messages.

Codebase for Overcooked simulator has been refactored. File rearrangement includes deletions and renaming to better reflect their functionalities. Within the code, several updates are made like support for using both file paths and direct strings as configurations. These amendments improve the organization, modularity, and overall efficiency of the code.
