remove: remove stats/base/sdsmeanors

This commit removes `@stdlib/stats/base/sdsmeanors` in favor of `@stdlib/stats/strided/sdsmeanors`.

BREAKING CHANGE: remove `stats/base/sdsmeanors`

To migrate, users should update their require/import paths to use
`@stdlib/stats/strided/sdsmeanors`, which provides the same API and implementation.

Ref: #4797
