/*
  This  webworker bundle is part of the libarchive.js module,
  so we need to make sure that it is available in the public (static) directory,
  since it will not get bundled if you're using a bundler tool such as webpack
  (it's all bundled up already) and specify the correct path in Archive.init() method.
