feat: migrate to pymodbus 3.11.4 and update bioyond configs
PyModbus 3.x Migration: - Copied modbus.py and client.py from dev branch for compatibility - Rewrote FLOAT32 decoding using struct module in coin_cell_assembly.py - Fixed STRING decoding for QR codes (battery and electrolyte barcodes) - Tested successfully on hardware with correct data decoding Bioyond Studio Updates: - Updated bioyond_studio config.py - Modified bioyond_cell_workstation.py - Enhanced warehouse.py and decks.py - Added README_WAREHOUSE.md documentation Parameter Enhancements: - Enhanced coin_cell_workstation.yaml parameter descriptions - Added matrix position ranges and indexing rules Breaking changes: - Requires pymodbus >= 3.9.0 - Removed deprecated BinaryPayloadDecoder/BinaryPayloadBuilder - Updated to use client.convert_from/to_registers() methods
