* Result of a single iteration of [`CodePointRangeIterator`].
* Logically can be considered to be an `Option<RangeInclusive<DiplomatChar>>`,
*
* `start` and `end` represent an inclusive range of code points [start, end],
* and `done` will be true if the iterator has already finished. The last contentful
* iteration will NOT produce a range done=true, in other words `start` and `end` are useful
* values if and only if `done=false`.
