 * Rewriter-Modul für Kontoauszüge der 1822direkt-Bank (und vielleicht andere). Die
 * Kontoauszüge können nicht geparst werden, weil das verwendete SWIFT-Format von
 * dem in der HBCI-Spezifikation vorgeschriebenen Format abweicht. Dieses Modul
 * korrigiert die Fehler in den Kontoauszugsdaten, so dass Kontoauszüge mit
 * HBCI4Java wieder zu parsen sind.
