Typos in utils.metrics.compare_to_actual function

[gedeon1310]

There might be typos in utils.metrics at lines 340 and 348 (_compare_toactual function)

I assume this shoulde be:

(340) _results['median_absolute_error'] = medae instead of _results['median_absoluteerror'] = rmse (348) _results['mean_absoluteerror'] = mae instead of _results['mean_absoluteerror'] = rmse

Thanks for the great repo !
