    on regarde les adherents sur leur addresse emails
    on regarde si l'id de payment n'a pas déjà été traité

    on regarde quelle est la période d'adhesion en cours
    première étape:
        on regarde si le member existe déjà à partir de son email
        si non, on ajoute le member
        ensuite on regarde si le membre a déjà adhéré pour cette période
        on regarde également si il n'y a pas un id existant helloasso (sanity check)
        si oui, on discard
        sinon, on ajoute la cotisation pour cette année
