- Adds a [SAX interface](https://json.nlohmann.me/features/parsing/sax_interface/index.md) and a non-recursive parser.
- Adds parsing from wide-string types (`std::wstring`, `std::u16string`, `std::u32string`), conversion to `std::string_view` (C++17), and round-tripping of `std::map`/`std::unordered_map` with non-string keys.
