/**
* The `useStateMachine` function is a TypeScript function that creates a state machine and returns the
* current state and a dispatch function to update the state based on events.
* @param initialState - The `initialState` parameter is the initial state of the state machine. It
* represents the starting point of the state machine's state.
* @param machine - The `machine` parameter is an object that represents a state machine. It should
* have keys that correspond to the possible states of the machine, and the values should be objects
* that represent the possible events and their corresponding next states.
* @returns The `useStateMachine` function returns an object with two properties: `state` and
* `dispatch`.
