feat: add testing framework with reference project integration

- Add test/ directory with test harness and test files - Add UDT, DB, FB parser tests - Add PLC JSON and integration tests - Test against reference project (239 UDTs, 12 DBs, 37 SCL, 13 XML) - Fix attribute parsing to handle underscores (S7_SetPoint) - Add ORGANIZATION_BLOCK support to FB parser
