json_serializer: Disable exceptions

Browse Source 
Define `JSON_NOEXCEPTION` to avoid raising exceptions.
Exceptions are usually disabled for Google projects (https://google.github.io/styleguide/cppguide.html#Exceptions).

Also pass `false` to the `allow_exceptions` parameter of `nlohmann::json::parse()`.

Issue identified by @kuafuwang in #26.
