[FEATURE] Minor Updates Through Overwriting config.json

[Mikefly123]

Story

• As a Mission Operator.
• I want be able to overwrite the configuration settings of the satellite.
• So that I can change its behavior in flight without updating any of the code in runtime.

Acceptance Criteria

• Add a new command to cdh.py that handles configuration updates
• Add a new command to cdh.py that returns the current version and last modified date of the software and config files
• Add to config.py a way to temporarily update a configuration variable (in RAM until the next reset)
• Add to config.py a way to permanently overwrite a configuration variable in config.json (update that is persistent through resets)
• Implement out of range error handling to block configuration updates that could create unhandled exceptions

Technical Details

• [Prerequisite] CircuitPython File System Read / Write Utilities
• [TASK] Merge utilities.py with the Main Codebase for File System Manipulation #122

Changing configuration variables is one of the safer ways to change the behavior of the satellite without having to inject new code into the runtime. This can include very simple changes like changing the critical_battery_voltage to a different value or more significant changes like changing the frequency that the radio is operating on.

One of the things to potentially consider when implementing this framework is thinking about how to handle safely updating configuration settings to ensure that there is a minimal risk that a user might accidentally push and update that will end up locking them out of the system. Thinking about how to architect that will probably be the bulk of the difficulty of this task.

Required Hardware

• Any Version of the Flight Controller Board
