🚀 Feature

Could we print out the maximum F1 score and the associated confidence threshold at the end of training?

Motivation

This is something that should be done for every custom model, and the data is readily available after the final mAP calculations, and PR curve drawing.

Pitch

Filter detections at different score/confident thresholds, calculate P/R/F1, and then print the optimal threshold (max f1).

Alternatives

Instead of printing max PR, maybe write a csv in the run directory, containing metrics at different thresholds.
