This commit updates the `QAgent` class to ensure that the Q-table is initialized for new states during the Q-learning update process. Additionally, a new `README.md` file is added to the `agents` directory, providing an overview of the agents module, including descriptions of various agent types and usage examples. New test files for `AlgoAgent`, `DeepQAgent`, `QAgent`, and `RandomAgent` are also introduced to enhance test coverage for the agent functionalities.
