// - "Optimisied member setters" are not usually generated until after an instance of a type has been serialised without, in which case all
// field names will have appeared in the serialised data at least once, which is important because the member setters will write out Name
// Reference IDs for fields and the reader needs to know what strings those IDs map on to. Since this code won't be serialising an instance
// of each type before using the member setter, FieldNamePreLoad data can be injected into the start of the serialised data and then the
// reader will be able to refer to use that to map IDs to strings.
