 2. BKON further compressed with LZ4 (a clean 90% reduction).
 3. The raw JSON file as fetched from a random data source.
-4. BKON decompressed once again to JSON. Note that this file is a little larger than the original JSON file as it contains a lot more decimal places due to float conversion precision.
