SimpleAggregateFunction Now Supports sumMap

Why it matters

This feature allows users to leverage the sumMap aggregate function inside SimpleAggregateFunction, simplifying the creation of aggregate functions that combine mapping and summation behavior efficiently. It enhances flexibility and expands the set of aggregate functions compatible with SimpleAggregateFunction, providing more powerful aggregation options.

How to use it

Use SimpleAggregateFunction by specifying sumMap as the inner aggregate function, for example: SimpleAggregateFunction('sumMap', ...). This enables aggregation using the sumMap logic wrapped within the SimpleAggregateFunction interface.
