v5.0.4

What's Changed

Fixed support for setting "init only" parameters using config option of createWorker (#862)
- For example, load_number_dawg is an "init only" parameter that cannot be set using either worker.setParameters or the options argument of worker.recognize.
- However, load_number_dawg can be set by the following createWorker statement.
  - createWorker('eng', "0", {}, {load_number_dawg: "0"});
