Jonas/127 replace all panics by fatal error

• Création d'un commite par crate
• Dans lib/core/conf ajout de commentaire pour les fonction ne pouvant pas utiliser la macro fatal_error car le logger n'est pas encore initialisé.
• Donc les seuls endroits où la macro panic! est encore utilisé:
  • avant l'initialisation du logger (donc la macro fatal_error ).
  • dans les tests (unitaire et intégration)
  • dans la crate lib/core/core car dev en cours https://git.duniter.org/nodes/rust/duniter-rs/tree/elois/ref-core-starter
