AggregateFunctions: implemented topK(n)
...
This implements a new function for approximate
computation of the most frequent entries using
Filtered Space Saving with a merge step adapted
from Parallel Space Saving paper.
It works better for cases where GROUP BY x
is impractical due to high cardinality of x,
such as top IP addresses or top search queries.
