Quick update: after three years, I was able to finish implementing all the targeted features. While the library may not win any benchmarks, the JSON trees are at least more space-efficient than std/json, and the implementation is solid. Every function is covered with test cases. I've also renamed the project to [jsonpak](https://github.com/planetis-m/jsonpak).
