ZOrderingSpec:
+ https://iceberg.apache.org/docs/1.4.2/spark-procedures/ 
A table with no particular order
- should have z-ordered files after rewriting the data
  + Given 40000 rows of data that look like
			Datum(6919,label_6919,4,2005-12-06,2024-11-15 17:11:23.592)
			Datum(12167,label_12167,2,1991-07-25,2024-11-15 17:28:53.192)
			Datum(32111,label_32111,1,1936-12-16,2024-11-15 18:35:21.992)
			...
are initially written to table 'polaris.my_namespace.ZOrderingSpec' 
  + When we execute the SQL:
CALL system.rewrite_data_files(table => "polaris.my_namespace.ZOrderingSpec",
strategy => 'sort',
sort_order => 'zorder(id, date)',
options => map('min-input-files','4', 'target-file-size-bytes','49152')
) 
  + Then added to the original 4 files are:
