Description
### Describe the enhancement requested
Presently, `Dataset` has methods to perform several actions—`sort_by`, `join`, and `join_asof`—with Acero. It would be especially helpful to provide a method to perform aggregations on datasets using Acero for convenient out of core processing.
The implementation can be modeled off of the existing `Dataset` Acero operations as well as the `aggregate` method of `TableGroupBy`.
