Using this makes runtime of mean and other similar calculations about 5-7 times faster on large images such as 24k x 24k that I use for the SKA reference run. Overall it improves performance by ~~15% in the current run (consistent with expectations given time in these functions and that the submaps do not gain from this optimisation)
