Increase scaling factor for loss components in espfit.app.train.report_loss()

[kntkb]

In espfit.app.train.report_loss(), the loss components are scaled by 100 because the values are very small and want to improve readability. However, we might want to scale this with a larger number??

df_new = df_new.mul(100)   # Multiple each loss component by 100. Is this large enough?
