Guide contributeur

Direction de recherche: Inspectez l'implémentation de la méthode dither565 dans Jimp pour confirmer qu'elle applique correctement l'algorithme de tramage. Vérifiez si la méthode modifie l'image sur place ou renvoie une nouvelle image, et assurez vous que l'opération d'écriture est appelée après la fin du tramage. Utilisez le débogueur ou console.log pour tracer les données de pixels après le tramage.
