\brief Concrete type class for sparse union data A sparse union is a nested type where each logical value is taken from a single child. A buffer of 8-bit type ids indicates which child a given logical value is to be taken from. In a sparse union, each child array should have the same length as the union array, regardless of the actual number of union values that refer to it. Note that, unlike most other types, unions don't have a top-level validity bitmap.
