worker does not terminate

[yetzt]

after worker.getFileInfo is done, the worker does not terminate and there is no way to terminate the worker.

Hi! I didn't mention it in the readme, but you can use worker.terminate() to terminate the worker

thanks!

would be nice if it could be fed with buffers instead of files only.

For the browser, I believe it should be an easy change to support ArrayBuffer or Blob. For node.js I'm not sure if I can do it, but I will try.
