/*
Externalizable Person
Класс Person должен сериализовываться с помощью интерфейса Externalizable.
Исправь ошибку сериализации.
Сигнатуры методов менять нельзя.


Требования:
1. Класс Solution.Person должен поддерживать интерфейс Externalizable.
2. Методы readExternal и writeExternal должны позволять корректно сериализовывать и десериализовывать объекты типа Person.
3. В классе Solution.Person должен быть создан конструктор без параметров.
4. В классе Solution.Person должен быть создан конструктор с тремя параметрами (String firstName, String lastName, int age).
