Support UBJSON-derived Binary JData (BJData) format (#3336)
* support UBJSON-derived Binary JData (BJData) format
* fix Codacy warning
* partially fix VS compilation errors
* fix additional VS errors
* fix more VS compilation errors
* fix additional warnings and errors for clang and msvc
* add more tests to cover the new bjdata types
* add tests for optimized ndarray, improve coverage, fix clang/gcc warnings
* gcc warn useless conversion but msvc gives an error
* fix ci_test errors
* complete test coverage, fix ci_test errors
* add half precision error test
* fix No newline at end of file error by clang
* simplify endian condition, format unit-bjdata
* remove broken test due to alloc limit
* full coverage, I hope
* move bjdata new markers from default to the same level as ubjson markers
* fix ci errors, add tests for new bjdata switch structure
* make is_bjdata const after using initializer list
* remove the unwanted assert
* move is_bjdata to an optional param to write_ubjson
* pass use_bjdata via output adapter
* revert order to avoid msvc 2015 unreferenced formal param error
* update BJData Spect V1 Draft-2 URL after spec release
* amalgamate code
* code polishing following @gregmarr's feedback
* make use_bjdata a non-default parameter
* fix ci error, remove unwanted param comment
* encode and decode bjdata ndarray in jdata annotations, enable roundtrip tests
* partially fix ci errors, add tests to improve coverage
* polish patch to remove ci errors
* fix a ndarray dim vector condition
* fix clang tidy error
* add sax test cases for ndarray
* add additional sax event tests
* adjust sax event numbering
* fix sax tests
* ndarray can only be used with array containers, discard if used in object
* complete test coverage
* disable [{SHTFNZ in optimized type due to security risks in #2793 and hampered readability
* fix ci error
* move OutputIsLittleEndian from tparam to param to replace use_bjdata
* fix ci clang gcc error
* fix ci static analysis error
* update json_test_data to 3.1.0, enable file-based bjdata unit tests
* fix stack overflow error on msvc 2019 and 2022
* use https link, update sax_parse_error after rebase
* make input_format const and use initializer
* return bool for write_bjdata_ndarray
* test write_bjdata_ndarray return value as boolean
* fix ci error
