Customizing behaviour on incorrect type in JSON about json_dto

[omartijn]

Thinking about this a bit, we'd probably have to ensure that we have the Reader_Writer parameter for all (read|write)_json_value functions. It's now there for some (i.e. std::optional and std::vector) but not for others (i.e. std::string).

Then we can define a member function to invoke if the type is incorrect, which in the default implementation would throw. Do you think that makes sense?

Hi!

My first thought is to use a special Reader_Writer implementation that checks the type of a value in rapidjson::Value and then reads it or uses a default value.
