Adding elapsed time for epochs when verbosity > 1

[beekill95]

When verbosity is set to 1, tqdm progress will show elapsed time for an epoch:

Epoch 1/50 - Finished: 100%|██████████| 47/47 [02:02<00:00,  2.61s/it, critic_loss=1.1245; generator_loss=1.2763; val_critic_loss=0.6452; val_generator_loss=0.9401; val_abs_diff=0.6452]

but this isn't the case when verbosity > 1:

Epoch 1/100 - Finished: path_loss=1.4134; time_loss=0.1531; loss=0.7833; val_path_loss=0.3029; val_time_loss=0.0318; val_loss=0.1673

It would be nice if we can add that information here.
