Back-compat alias for AggregateMap. Before v0.23.0 the
{ from, using } (renamed-output / multi-reducer) form lived on a
separate AggregateOutputMap type and a separate overload. The two
are now unified into AggregateMap, which accepts both the
shorthand and spec forms (and mixtures). Retained as an exported alias
so existing imports keep resolving.
