Fix missing evaluation dependencies (exec_eval.py, parse.py) from test-suite-sql-eval

[ewerthonk]

Description

Hello team! I am currently reading through your paper and am looking to use ETM as the evaluation metric for my master's degree research on Text-to-SQL tasks.

While testing the repository locally to evaluate some sets, I encountered a missing dependencies issue with the evaluation script, specifically failing to locate [exec_eval.py] and parse.py logic which seemed to be missing from ETM_utils.

After some research, I found that these files originated from the taoyds/test-suite-sql-eval repository. This pull request adds the missing evaluation scripts directly into ETM_utils/ and updates the internal imports in my fork to ensure the [treeMatch.py] evaluator works successfully out of the box when ran locally.

I've tested the changes locally and confirmed that it executes and returns the scores successfully.

Changes Included

• Added [ETM_utils/exec_eval.py] and ETM_utils/parse.py from the test-suite-sql-eval suite.
• Re-organized any related local imports in [ETM.py] and [evaluation.py] to point to the correct evaluation module path.

Thank you for providing the repo to the community, hoping this helps anyone else trying to run the evaluations locally.
