This PR currently contains smeankbn, as well, which is not desired. I suggest removing smeankbn changes, as those have already been merged.

@MeKaustubh07 Additionally, rather than dmaxsorted and using AI, I would suggest copying the much more closely related package @stdlib/stats/base/ndarray/dmeankbn2 and not use AI. If you copy that package, you can easily do a find-and-replace without the need for AI assistance.
