"""
Dumps a SDRangel instance configuration to a sequence of commands in a JSON file
compatible with config.py
Each command is a JSON document with the following keys:
- endpoint: URL suffix (API function) - mandatory
- method: HTTP method (GET, PATCH, POST, PUT, DELETE) - mandatory
- params: pairs of argument and values - optional
- payload: request body in JSON format - optional
- msg: descriptive message for console display - optional
- delay: delay in milliseconds after command - optional
