Adding evaluation metrics such as F1 score, ROC AUC.

As continual learning is expanding in its domain from Vision to others. I think including some common metrics such as F1 score, ROC- AUC would be quite useful while experimenting on Imbalanced Datasets.

Your are totally right. We are already working on expanding our base set of metrics (e.g. #212 #213 ). We will definitely take into consideration F1, ROC and AUC.
