Can't use highlighting in a WebWorker

[georeith]

Since the top level fuzzySort.highlight was replaced in favor of result.highlight you can no longer computer results in a WebWorker and highlight them back in the main thread because the highlight function is removed during the structured clone in postMessage().

When you're using something like React it isn't as simple to perform the highlighting in the worker.

In the meantime I'm using React's startTransition to help unblock the UI and it works well, just wanted to note the limitation.
