Python: calibration tool — ligne orange pic dernier tir + titre simplifié

Browse Source 
Ajoute une ligne horizontale orange sur chaque graphe indiquant le niveau
atteint au moment du dernier tir détecté, avec % du seuil dans le titre.
Permet de comprendre pourquoi un tir est déclenché même si le pic BLE
(20Hz) ne semble pas dépasser le seuil (résolution temporelle limitée).
Supprime le pic 1s (remplacé par le pic dernier tir, plus pertinent).
