/**
 * A script that helps with reformatting the JSON data pulled from QDC's chapters API e.g. https://api.quran.com/api/v4/chapters?language=ar
 * to QDC's FE JSON structure. This will help us:
 *
 * 1. Camelize the keys.
 * 2. Remove un-necessary data to make the payload size as small as possible.
 *
 * It can be used by running `yarn run chapter-data:format {locale}` e.g. `yarn run chapter-data:format en`
 * after having created a file called `data/chapters/en.json` and pasted the API's JSON response into it.
