Description

This pull request includes several changes to add weather variability configuration logging, update version numbers, and improve test coverage. The most important changes are grouped into three themes: logging enhancements, version updates, and test improvements.

Logging Enhancements:

• Added weather_variability_config.json to the output directory to log weather variability configurations for each episode.
• Introduced weather_variability_config attribute in modeling.py to store weather variability configurations.
• Updated apply_weather_variability method to assign variability configurations to self.weather_variability_config.
• Added weather_variability_config_path in wrappers.py and updated dump_log_files method to log weather variability configurations if they exist. [1] [2]

Version Updates:

• Updated the version from 3.7.2 to 3.7.3 in pyproject.toml and version.txt. [1] [2]

Test Improvements:

• Modified test_apply_weather_variability to remove checks for the existence of weather_variability_config.json.
• Enhanced test_CSVlogger_wrapper to include parameterized tests for different environments and to check the creation of weather_variability_config_path. [1] [2] [3]
