* Conform `std::iterator_traits<fmt::appender>` to [iterator.traits]/1

> shall be defined as the iterator’s pointer and reference types; that is, for an iterator object `a` of class type, the same type as `decltype(a.operator->())` and `decltype(*a)`, respectively. The type `iterator_traits<I>::pointer` shall be void for an iterator of class type `I` that does not support `operator->`. Additionally, in the case of an output iterator, the types

> iterator_traits<I>::value_type
> iterator_traits<I>::difference_type
> iterator_traits<I>::reference
