Fix: issue crash in code gen with incorrect column length in decision trees (#1069)

* Fix: Deeply nested assignments would offset the new columns count calculation. Now we track relevant columns and their path to ensure each row has wildcards if they don't contain the relevant column

* Add test plus clippy fix

* Clippy fix

* New version clippy fix
