/**
 * Normalizes Firestore Timestamp objects and Buffer objects in a data structure
 * by replacing them with standardized string representations.
 *
 * This is useful for creating deterministic snapshots in tests where the
 * actual
 * timestamp/buffer values may vary but their relative ordering or content
 * is what matters.
 *
 * - Timestamps are replaced with strings in the format `/Timestamp XXXX/` where
 *   XXXX is a zero-padded index representing the timestamp's position when all
 *   timestamps are sorted chronologically.
 * - Buffer objects are normalized to `/Buffer <base64url>/` format.
 *
 * @param data - The data structure containing Timestamp and Buffer objects
 *   to normalize
 * @param options - Optional configuration for the normalization process
 * @returns A new data structure with all Timestamps and Buffers replaced by
 * normalized strings.
