Workers are implemented on ESP8266 and ESP32. They aren't in the simulator yet. It is some non-trivial work for each host platform to do that. But, the error isn't very helpful. I'll update the manifest so it fails more gracefully.

Mac build for worker now gives a real error:

# error: Worker unsupported!
### Error: incompatible platform!
