-; Modbus
-;  Creates the file modbus_entity_parameters.hpp
-;  Creating the modbus registers is a multi-step process. Before it was in a shell script called generate_csv_and_headers.sh
-;  but now moved to pio so everything is in python and cross-platform. The logic is as follows:
-;  1. create a dummy modbus_entity_parameters.hpp file so the first pass compiles
-;  2. compile the EMS-ESPcode with the EMSESP_MODBUS flag set
-;  3. run the entity_dump test command and generate the dump_entities.csv file
-;  4. use the dump_entities.csv file with update_modbus_registers.py script to generate the modbus_entity_parameters.hpp file
-;  5. clean up everything and start again with the EMSESP_STANDALONE flag set
-;  6. run the entity_dump test command again to create the real dump_entities.csv file
