Mode for topK/topkWeighed with counts and error support

Why it matters

This feature addresses the need for users to obtain not only the most frequent values but also the counts and error margins associated with those counts, enhancing the accuracy and reliability of data aggregation results.

How to use it

To use this feature, apply the new support mode available in the topK and topKWeighted functions. This mode will return the count of values together with an error estimate, enabling you to assess the accuracy of the aggregated data.
