/**
 * Base class for Binary CSV Parsers.
 * Provides common implementation for both object and array output formats.
 * Combines TextDecoder with StringCSVParser for binary data parsing.
 *
 * @template Header - The type of the header row
 * @template Format - Output format: 'object' or 'array'
 *
 * @remarks
 * This is an internal base class. Use FlexibleBinaryObjectCSVParser or
 * FlexibleBinaryArrayCSVParser for concrete implementations, or use the
 * createBinaryCSVParser() factory function for type-safe instantiation.
 *
 * Uses {@link BinaryCSVProcessingOptions} which excludes execution strategy (engine).
 * Low-level parsers focus on CSV processing logic only.
