porting jsonata-cpp to use QJson instead of nlohmann json library #3

Hi,

I am modify your library to support schema validation with Qt Json backend instead of nlohmann. however that is not the problem.

I develop under windows MSVC2022 and got assert errors when running the tests.

when running jsonata_generated_tests with the nlohmann backend (not the Qt one ) I get test errors :

one I fixed by updating the tokenizer.cpp:379 regex_match (using &*byteEnd is not allowed under msvc)

I also have a test failure with $formatinteger(1e46,'w') which causes integer conversion issues and then std::vector index problems (the converted value is negative).

I also have a test failure :

can you tell me how to treat these test cases ?
