title: How to load .zip files into BigQuery?
body: <p>We are able to load uncompressed CSV files and gzipped files completely fine.
  However, if we want to load CSV files compressed in ".zip" - what is the best approach to move ahead?
  Will we need to manually convert the zip to gz or BigQuery has added some support to handle this?</p>
  
  <p>Thanks</p>
