Split Data Release Bundle in to multiple gzips

Considering the growth of data and Network accessibility required for downloading the data release bundles we want to split the data release output file in multiple batches.

May be restrict bundle sizes to 500MB. The compressed bundle size is ~ 2 GB for 350000 Samples (10 GB actual data)

Start with the data release generation entry point identified by the repository and trace how the single compressed bundle is produced. Define how output should be divided into batches of about 500 MB, then verify that a release containing 350,000 samples can be generated and downloaded as multiple gzip files.
