refactor: update sketchlib import paths for top-k module renames

Tracks the module renames in asap_sketchlib PR #39:
- sketches::countmin     -> sketches::countminsketch
- sketches::cms_heap     -> sketches::countminsketch_topk

Type names (CountMinSketch, CountMinSketchWithHeap, CmsHeapItem)
are unchanged.
