Fix compile with we use QT_DISABLE_DEPRECATED_BEFORE=0x060000 in apps

in qt5.15 you deprecated iterator &operator--() in qhash
but QDataStream needs it. (see writeAssociativeContainer)

So when we compile without deprecated method we can see:
qdatastream.h:333:9: error: no match for ‘operator--’ (operand type is ‘QHash<QString, QImage>::const_iterator’)
  333 |         --it;
      |         ^~~~

The current code is only

QHash<QString, QImage> m_images;
QDataStream stream(&file);
stream << m_images;
