True when any of the flake's projected flakes carries an
aggregate transform along its pipe. A single
aggregate projection switches the whole query to grouped semantics: the non-aggregate projections become the
grouping keys (see getFlakeGrouping) and the aggregates reduce each group. Scans the projection set across
the tree, unlike isAggregateFlake, which tests one node.
Checks whether a Flake groups the query.
