[ATR-28079] Update thinning logic for trigger DAOD PHYS/LITE in order to save more disk space

Tim Martin requested to merge tamartin/athena:furtherDAOD_PHYS_TrigNav_SizeReduction into main

We currently save the InputMaker node immediately preceding the final Hypo node - this is in case we need access to the final feature's ROI which is linked as an edge from the InputMaker node.

With this change we drop this InputMaker node, but we preserve the knowledge of the ROI by copying this edge down to the Hypo node.

By no longer saving the InputMaker, we also resolve a nasty TODO in the recursive function logic.

Example before: image

Example after: image

This change should save some disk space (TBC) without otherwise changing the functionality of the trigger data in the derivation.
