/**
 * Parses a human-readable data size string into bytes.
 * Supports various units: B, KB, MB, GB, TB, PB, EB, ZB, YB.
 *
 * @param input - The data size string to parse (e.g., "5KB", "10 MB", "1.5GB").
 * @param binary - Whether to use binary (1024) or decimal (1000) multiplier (default: true).
 * @returns The size in bytes.
 *
 * @throws {Error} If input is empty.
 * @throws {Error} If input format is invalid.
 * @throws {Error} If the numeric value is negative or NaN.
 * @throws {Error} If the unit is not recognized.
 *
 * @example
 * // Basic usage
 * parseDataSize("5KB"); // Returns 5120 (binary)
 *
 * @example
 * // With decimal multiplier
 * parseDataSize("5KB", false); // Returns 5000
 *
 * @example
 * // With spaces
 * parseDataSize("10 MB"); // Returns 10485760
 *
 * @example
 * // Fractional values
 * parseDataSize("1.5GB"); // Returns 1610612736
 *
 * @example
 * // Case insensitive
 * parseDataSize("2kb"); // Returns 2048
 *
 * @note Units are case-insensitive. Whitespace between number and unit is optional.
 * Binary mode (default) uses 1024 multiplier, decimal mode uses 1000.
 *
 * @complexity Time: O(1), Space: O(1)
