Merge generate-data into main project (danvk#141)

- Translate existing `generate-data` NPM scripts to JavaScript functions
- Remove `foo.1234.js` because it's the same as `foo.min.js`
- Add `sourcesContent` to `map-reference-eol.js` so that EOL can be checked
- Move frequently used NPM scripts to the top
- Add `test:generate-data` script to generate test data
- Update dependencies
- Add `Learn about source maps` section to README
