[hayleypark]

Issue #, if available:

Description of changes:

• Deprecate aggregate = True flag in src/stickler/structured_object_evaluator/models/comparable_field.py, src/stickler/structured_object_evaluator/models/comparison_info.py and src/stickler/structured_object_evaluator/models/configuration_helper.py (not currently used in calculation)
• Update exiting test cases for correct universal aggregate metrics calculation without changing the overall metrics related test cases
• Add a new test cases for universal aggregate metrics calculation (tests/structured_object_evaluator/test_ecommerce_orders_aggregate_comprehensive.py)
• Update the evaluator and the bulk evaluator to optionally use aggregate metrics
• Assumption: For aggregate metrics, all matched items (regardless of the similarity score) are considered. For overall metrics, only those above match threshold are considered.
• TODO: Implementation of the aggregation logic in src/stickler/structured_object_evaluator/models/structured_model.py and src/stickler/structured_object_evaluator/models/structured_list_comparator.py to pass these tests.
