DEPRECATED AND DEFUNCT

• Deprecate get_audit_report() in favor of get_audit_csv_report() (#62)
• Defunct create_dn(). This introduces a breaking change for
  list_principal_owner_citations() and list_user_data_packages(),
  which now require an EDI-ID instead of a Distinguished Name (DN). Users can
  obtain their EDI-ID by logging into the
  EDI Identity and Access Manager
  and copying the "EDI-ID" from their profile home page. (#65)

MINOR IMPROVEMENTS

• Update authentication to support new EDI IAM system (#60)
