Attempting to use a DateTime attribute within any @JsonCodable() annotated class throws an unsupported error. DateTime is a commonly used type in dart and other languages to represent timestamps for creation data points etc.

Consider the code:

@JsonCodable()
class Person {
  final DateTime birthday;
}

It throws the following errors:

Unable to deserialize type, it must be a native JSON type or a type with a `fromJson(Map<String, Object?> json)` constructor
Unable to serialize type, it must be a native JSON type or a type with a `Map<String, Object?> toJson()` method.

If supporting DateTime is not within the scope of this package, can you suggest a possible hack or workaround?
