[alinakbase]

Summary

This PR introduces a new PySpark-based pipeline for processing Gene Ontology (GO) annotation files and exporting the results to Delta Lake format. (Replace pandas with PySpark)

Changes Included

• New parser module: src/parsers/association_update.py

  • Parses GAF-like CSV annotation files
  • Handles qualifiers, evidence codes, publications, and metadata
  • Joins with ECO mapping for evidence type inference
  • Outputs a structured Delta table for downstream use
  • Supports optional table registration (--register) and temporary view mode (--temp)
  • Built with modular functions and a Click CLI entry point

• Test suite: tests/test_association_update.py

  • Unit tests for all core functions including:
    • Uses pytest.mark.parametrize for testing key transformation logic
    • Ensures correctness of date parsing, predicate normalization, and evidence joins
    • Designed to run with Spark local mode for lightweight CI validation
