 If you just want to serialize/deserialize some structs, the `to_json`/`from_json` functions can be a lot of boilerplate.

-  1. `NLOHMANN_DEFINE_TYPE_INTRUSIVE(name, member1, member2, ...)` is to be defined inside the class/struct to create code for. This macro can also access private members.
-  2. `NLOHMANN_DEFINE_TYPE_INTRUSIVE_WITH_DEFAULT(name, member1, member2, ...)` is to be defined inside the class/struct to create code for. This macro can also access private members. Falls back to the default value for the respective type of the member variable if a key in the JSON object is missing.
