Detailed Description

std::vector views and iterators that incorporate a type conversion

If the underlying column is an std::vector, but the access requires a type conversion (e.g. ElementLink or an enum), then I can't just use a std::span to access the data. Instead I rely on this view and iterator to handle the conversion on access. Presumably with C++23 this could be replaced with a range adaptor, but for now I need to do it manually.
