This implements `Statistics.median` based on the existing bitonic sorting, avoiding unnecessary allocation. While it is generally suboptimal to sort the whole array, the compiler manages to skip some branches since only the middle element(s) are used. Thus `median` is generally faster than `sort`. Using a dedicated median selection network could yield better performance and might be considered for future improvement.
