9373 * @brief Dissect a TypeLookup Request structure
9374 *
9375 * @details This function handles the dissection of a TypeLookup Request structure
9376 * following the OMG XTypes 1.3 * specification. It processes the request header
9377 * that contains a GUID, sequence number, and instance name, followed by request
9378 * data that varies based on the requested operation type (GET_TYPES or
9379 * GET_DEPENDENCIES). For GET_TYPES, it dissects a sequence of TypeIdentifiers
9380 * to look up; for GET_DEPENDENCIES, it additionally processes a continuation
9381 * point after the sequence of TypeIdentifiers. Each section is preceded by XCDR2
9382 * delimited headers for proper alignment and parsing.
9383 *
9384 * @param tree Protocol tree to add the TypeLookup Request elements to
9385 * @param pinfo Packet info for the current packet
9386 * @param tvb The tv buffer containing packet data
9387 * @param offset The current offset in the tvb
