feat(): entirely hide rapidjson symbols

It is used only internally, so they must be hidden from the global scope, but GCC exports them anyway, because of forced default visibility for all templates within std namespace. This commit applies custom symbol versioning mapping directly to the linker eliminating all rapidjson symbols from the global scope. Closes #78.
