fsm: add fsm module This commit adds a module for a finite state machine. The goal of the module is to provide a simple, easy to use, and easy to understand finite state machine. The module is designed to be used in future loop subsystems. Additionally a state visualizer is provided to help with understanding the state machine. 2023-08-23 09:27:23 +00:00			```mermaid
