Nodejs 17 breaks webpack 5

Nodejs 17 upgrades to OpenSSL 3.0, which removes the md4 hashing function that webpack 5 uses for hashing files.

To fix this, you can provide an alternative hashing function for webpack to use. Set output.hashFunction: 'xxhash64' in the webpack config. See: https://stackoverflow.com/a/73027407/2214847

However, setting this option does not fix the issue in our case, since react-pdf/dist/esm/entry.webpack.js loads its files via an unconfigurable file-loader, which uses the default md4...

So to fix this, we should both:

• Set output.hashFunction: 'xxhash64' in the webpack config to fix the general case
• Use an alternative wrapper for pdfjs which does not use the unconfigurable file-loader.
