Introduce container for default values #452

Closed frankmcsherry closed 7 months ago

frankmcsherry commented 7 months ago

This PR introduces a container that effectively represents a run of default values, and spills to a back-up container if non-default values are discovered. This is meant to be a MVP example of a non-trivial container that relies on GATs, but also has the potential to bring OrdVal and OrdKey spines closer together, at some CPU cost.

Thanks for the review (made the fixes!)
