Make the Error Warning and Trapping System a Python Package (NGWPC-9165)

[cmaynard-ngwpc]

The Error Warning and Trapping System was embedded in a single file in a subdirectory that required path knowledge in order to import the necessary references. This PR refactors this file into a Python package defined at the codebase top level src directory making it a cleaner and easier implementation of the logging system. Created unit tests for the new package.

Additions

• Created src/lstm_ewts subdirectory containing the pyproject.toml file
• Created the src/lstm_ewts/src/lstm_ewts containing the __init__.py file defining the public API for the package along with new package module files constants.py, paths.py, formatter.py, and config.py containing the refactored logger.py logging code.
• EWTS unit tests in test/lstm_ewts

Removals

• The original logger.py file has been deleted.

Changes

• Updated import statements in the code base to use the new lstm_ewts package.
• Updated the GitHub Unit Test runner to properly include the new lstm_ewts package when doing the pip install

Testing

1. Tested running ngen stand-alone and building the containers to run ngenCERF. LSTM fails in T-Route when running standalone and in ngenCERF due to a realization file error, both of which are being addressed in bug ticket (NGWPC-9080) and unrelated to the Error, Warning and Trapping System. This can be merged while the bug ticket are worked.
