Qt Json 1.3.5

What's new

• Small compiler warning fixups for C++20.

---

To use this library:

• Just put Json.cpp, Json.h, Json_Parser.cpp into your project. Requires C++17 and Qt5 or Qt6.

Optionally If you wish to use the SimdJson backend for even faster parsing:

• Also copy simdjson/simdjson.cpp and simdjson/simdjson.h into your project (and make sure that Json_Parser.cpp can see these files).
