KAPLIBS: Fix two bugs in deriving clipped means.
+ It now also calculates the true weighted variance to derive the
clipping limits in a single loop. It had previously used the
"population variance" (the variance of the mean) not only for the
returned variances, but also for the clipping. This statistic
could be much smaller than the nearest values about the mean,
hence leading to apparently no good values, and a bad pixel
appearing in the output data.
+ Fix bug introduced recently (168a52687eede) when reordering
summations for efficiency. I thought I had seen one missing
replacement, but then lost it. In a weird fashion it caused the
pixels in the output array to shift along by one pixel with the
original last column appearing as the first.
