Detailed Description

Header for utility functions and type definitions used in PU1 suppression logic.

This module defines the core types and declares helper functions for:

• Converting between binary, hexadecimal, and numeric types
• Extracting and manipulating TOB fields
• Running suppression simulations based on LUT thresholds
