Add detail::exception_id, a scoped enum with one named enumerator per documented exception id, and use it for every id in the library. The create() functions get an overload for it; the int overloads stay for user code. Following the review of #5783: add binary_reader::invalid_byte() and length_type_error(), basic_json::throw_subscript_wrong_type(), move the fuzzer includes and the using-declaration into fuzzer_common.hpp, and rename test_sax.hpp to sax_event_loggers.hpp. Signed-off-by: Niels Lohmann <mail@nlohmann.me>
