cli: Rearrange columns in csv formatted benchmark report
Reorder the multi-index columns in the csv report, so that for every sut/swprofile we get the summary statistics, such as min, max, mean, std deviation etc. grouped together.
This improves the readability of csv formatted fastpath results, especially when dealing with large data sets containing multiple swprofiles or suts, such as bisection results.
