   ## Jira Link
   
   [CALCITE-7583](https://issues.apache.org/jira/browse/CALCITE-7583)
   
   ## Changes Proposed
   
   The semantics of UNNEST was wrong according to the SQL standard, and 
according to all implementations I checked. This PR replaces the "cartesian 
product" semantics of UNNEST with a "zip and pad" semantics, where multiple 
collections are zipped and padded to the length of the longest collection
   
   The actual implementation parallels in many ways the previous product 
implementation, it just uses a different Enumerable.
   
   The previous implementation FLAT_PRODUCT is now unused, but since it's 
public I didn't remove it.
