Creates a TypedColumn that computes the means by key of a Dataset column of type Seq[Map[String, Double]].
Creates a TypedColumn that computes the means by key of a Dataset column of type Seq[Map[String, Double]]. Each map has a separate mean by key computed. Because each map does not have to have all the possible keys, the element counts for each map's keys can all be different.
