Keeps track of the requested physical column IDs and their in-memory target type via a column element identifier.

When using alias columns (projected fields), physical columns may be requested multiple times.

Maps physical column IDs to all the requested in-memory representations.

A pair of physical column ID and in-memory representation can be requested multiple times, which is indicated by the reference counter. We can only have a handful of possible in-memory representations for a given column, so it is fine to search them linearly.
