/**
 * @fileoverview MPN (Most Probable Number) Lookup Tables and Functions
 *
 * This module provides lookup tables and functions for calculating Most Probable Number (MPN)
 * values for different types of microbiological testing:
 *
 * - Standard quantification (getQtMpn)
 * - 2000-well format high-throughput analysis (getQt2KMpn)
 * - Legionella-specific testing (getQtLegio)
 *
 * The arrays are kept as large static lookups for optimal performance and minimal memory usage.
