At the moment, webpack uploads and serves the mp3 files uncompressed.
If you run `npm run build`, you'll get a warning message:
WARNING in asset size limit: The following asset(s) exceed the recommended size limit (244 KiB).
This can impact web performance.
I would like to improve the webpack configuration to **compress the mp3 files and serve them on github pages**.
Perhaps this would work with `compression-webpack-plugin`: https://github.com/webpack-contrib/compression-webpack-plugin?
