Hi, thanks for the library! Very useful for working with sacred experiments.

Is there a way to specify multiple reducers for projection? Say, I want to get the min and argmin of a metric. Right now I can do one of them withquery_set.project(on=[{'metrics.loss': np.min}]) (or np.argmin) but not both because dicts only allow unique keys. Looking at the code, it doesn't seem supported yet. Would be nice if it is!
