Pull Request Overview

This PR introduces new unit tests for utility functions while refactoring hex‐string conversion and related helper methods to improve testability. Key changes include:

• Adding tests for IsValidHex, HexToIntList, IntRangeToIntList, and SelectiveIntRangeToIntList in internal/util/util_test.go.
• Refactoring hex conversion functions in internal/util/util.go and updating downstream callers in table_helpers.go and table_defs.go.
• Adding additional unit tests in target, report, and common directories to increase overall coverage.
