The code changes include renaming the 'category' field from "Cooking Equipment" to "ItemCookingEquipment" in sample_state.json. The documentation has also been updated with more detailed explanations on how the system works, including how to install and use it. A few function signatures were changed and additional explanation comments were included in the counters.py and utils.py files for better code clarity.

The updates include adding docstrings and type hinting to several classes and methods in multiple Python files. This commit also includes fixes for inconsistent code formatting and minor bugs. The docstrings provide essential details about the classes and methods, improving readability and understanding for other developers. Furthermore, the added type hinting will enable better IDE assistance, static analysis, and clarity on expected input and output types. Lastly, the code formatting fixes and bug fixes enhance the overall code quality and maintainability.

An argparse has been added to the overcooked simulator script for better configuration of the command line interface. This allows the user to input the state file, visualization configuration and output filename when executing the script. As a result, the need to manually update these parameters in the script has been mitigated.

Added sample json file for testing (could change/break in future), added saving images created from states.

This commit provides a significant overhaul of various aspects within the overcooked_simulator's 2D visualization and GUI components. The changes include adjusting the game window and grid size, simplifying the drawing methods by removing redundancy, and enhancing the theme configuration for the GUI. This makes the code cleaner and easier to maintain, besides improving the visual style of the GUI.

Refactored the transition filter code in overcooked_environment.py by replacing redundant code with a call to `filter_item_info` method. The changes lead to easier maintenance and increased code readability. Also, in gui_2d_vis/drawing.py, array conversion was added to 'pos' to ensure operations involving 'pos' and 'd' won't raise errors.

The CookingCounter is now included in the list of counters for which we calculate progress. Additionally, if a counter type is not defined in the configuration, a ValueError will be raised. Unnecessary imports were also removed from 'overcooked_gui.py', and a 'to_dict' method was added in 'counters.py'. Fixing errors from merge.

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`.
