Modbus FIFO Queue Response Handling

This module provides the logic for parsing and dispatching responses related to Modbus Read FIFO Queue (Function Code 0x18).

Responsibilities

• Parsing: Validates PDU structure, function codes, and byte counts for FIFO responses.
• De-encapsulation: Extracts the 16-bit register values from the Modbus PDU.
• Dispatching: Routes the parsed data to the application layer via the FifoQueueResponse trait.

Architecture

• ResponseParser: Contains low-level logic to transform raw PDU bytes into a list of register values.
• ClientServices implementation: Orchestrates the high-level handling, converting the PDU into a FifoQueue model and triggering the application callback.
