• BREAKING CHANGE: Networks with empty map or empty array data are now
  skipped by default. This makes the output cleaner when working with
  databases that use empty values for networks without meaningful data (e.g.,
  public IPs in some databases). Use the new -include-empty-values flag to
  include these networks in the output.
• Added -include-empty-values flag to optionally include networks whose data
  is an empty map or empty array.
