topn collector switch approach based on size+skip
we now use the slice store when size+skip <= 10
and use the heap store when size+skip > 10
here are the new perf numbers:
go test -run=xxx -bench=. -benchmem

BREAKING CHANGE - additional package renaming
i recently learned that package names should also prefer the
