Represents an unresolved object reference. This allows objects to be referenced by only their ID.
version and digest details may also be added to unresolved object references.
To fully resolve a reference, the correct ObjectArg type needs to be determined based on the type of object,
and how it used in the transaction (eg, is it used mutably if it's shared, and is it a receiving object if it's not shared)
