#Luua isikukoodi parser ja õigsuse kontroll.
#Sisendiks fail kus igal real on isikukood, mis võib olla õige või vale.
#Väljundiks on fail kus on õiged isikukoodid kus kontrollsumma klapib ning kuupäev on korrektne (aastas 12 kuud ning iga kuu päevade arv sobiv).
#
#NB! Kuupäeva õigsuse kontrollimiseks kasutage datetime.strptime funktsiooni ja uuesti vormindamiseks datetime.strftime funktsiooni
