Minor Changes

• #4198 ca58904ad Thanks @davidkpiano! - Introduce toPromise(actor), which creates a promise from an actor that resolves with the actor snapshot's output when done, or rejects with the actor snapshot's error when it fails.

  import { createMachine, createActor, toPromise } from 'xstate';
  
  const machine = createMachine({
    // ...
    states: {
      // ...
      done: { type: 'final', output: 42 }
    }
  });
  
  const actor = createActor(machine);
  
  actor.start();
  
  const output = await toPromise(actor);
  
  console.log(output);
  // => 42
