* Adapted from https://github.com/mozilla/pdfjs-dist/blob/e9492b7a725ec4edd466880223474f4295a5fb45/webpack.js
* The PDF.js worker needs to be loaded in a Web Worker. This can be done
* automatically with webpack via worker-loader.
* PDF.js has the above file to do this, however it uses the webpack loader
* module loading syntax, which prevents us from customising the loader.
* We need to output the worker file to the public/js directory, and so we need
* to customise the loader's options. However the rest of the file is identical
* to the one provided by PDF.js.
