Transform a zip operation of the form
Bind(s1, Join(jlsym, jrsym, l @ Bind(_, _, Pure(StructNode(ldefs), _)), r @ Bind(_, _, Pure(StructNode(rdefs), _)), JoinType.Zip, LiteralNode(true)), sel)
into an equivalent mapping operation using RowNum by first transforming both sides of the
join into zipWithIndex and then using transformZipWithIndex on those.

Transform a zipWithIndex operation of the form
Bind(s1, Join(_, _, Bind(ls, from, Pure(StructNode(defs), _)), RangeFrom(offset), JoinType.Zip, LiteralNode(true)), p)
into an equivalent mapping operation using RowNum.
Transform a zipWithIndex operation of the form
Bind(s1, Join(_, _, Bind(ls, from, Pure(StructNode(defs), _)), RangeFrom(offset), JoinType.Zip, LiteralNode(true)), p)
into an equivalent mapping operation using RowNum. This method can be overridden in
subclasses to implement non-standard translations.
