[FEATURE] CDH accept infinitely expandable list of commands

[nateinaction]

Story

• As a Satellite developer
• I want to add my own commands to a pysquared based satellite without needing to contribute directly to pysquared
• So that I can build my own functionality!

Acceptance Criteria

• Able to accept commands that don't live in pysquared
• Able to run functions for hardware that pysquared doesn't know how to interact with

Technical Details

Imagine that I'm a university that has developed a camera payload for pysquared. Camera functionality is not in built into pysquared. Instead of building all the functionality into pysquared.

Maybe something modifying __init__() to accept functions as arguments:

cdh(existing args, ("my_special_command", function), ...)

I wonder if we should have a protocol that defines what a command looks like?

class command:
  def get_name(): ...
  def run(args): ...
