If this class is extended by inheritance, calling the parent
read method will invoke the wrapper for this method and therefore invoke the associated internal callback. This allows the method to be overridden and or intercepted and filtered (for example, decrypting
$data value returned by the parent
For more information on what this method is expected to do, please refer to the documentation at SessionHandlerInterface::read().
