To avoid having to compose several required libraries together, it's simpler to use a single bundled JS file.
Use this package: https://github.com/pedrouid/starkware-crypto
Then either build locally and build the bundled file, or install through npm:
npm install -g starkware-crypto
Go to the installed library directory, (default /usr/local/lib/node_modules/starkware-crypto), then grab the single bundled JS file under dist/umd, so it's easier to inject into a JSContext
The file 'index.min.js' is here copied directly in project.
