La variable names contient un dictionnaire avec plusieurs personnes qui possèdent le même nom de famille.
Nous souhaiterions regrouper tous les gens avec le même nom de famille dans le dictionnaire resultat :
{
'Smith': ['Patrick', 'Clara', 'Michel'],
'Mercier': ['Julie', 'Rose'],
'Moulin': ['Maxime', 'Gérard', 'John']
