It is not very useful for iterative parsing as the worst case of heap
size is O(n) where n is number of character in JSON, for the worst
synthetic cases. This is reasonable and should not create stack overflow
security problem as in recursive parsing.
In order to enable the customization of the error macros
- RAPIDJSON_PARSE_ERROR_NORETURN
- RAPIDJSON_PARSE_ERROR_EARLY_RETURN
the user may need to have access to the ParseErrorCode enum
already. This requires a separate header location than the
GenericReader.
Parse errors is represented as enum type `ParseErrorCode`.
Error texts are optional for user.
Added `GetParseError_En()` in `error/en.h`, user can localize this file
into other files. User may dynamically change the locale in runtime.
