The aggregators had incorrect types for getResultType when shouldFinalze is false. They had the finalized type, but they should have had the intermediate type. Also includes a refactor of how ExprMacroTable is handled in tests, to make it easier to add tests for this to the MSQ module. The bug was originally noticed because the incorrect result types caused MSQ queries with DS_HLL to behave erratically.
This module provides Druid aggregators based on https://datasketches.apache.org/.
