post_summary.csv files generated by ultranest logging have out of order data values

logging post_summary.csv files generated by ultranest when specifying a logging directory in ReactiveNestedSampler have values different from what what the column names suggest.

The ultranest documentation suggestions that you can ingest these files with pandas.read_csv() to get out the summary statistics for the fitted parameters. These files have column names along the lines of: param_1_mean, param_1_stdev ... param_2_mean, param_2_stdev...

Instead, it looks like the data values are organized as: param_1_mean, param_2_mean ... param_1_stdev, param_2_stdev...

so when you ingest them you get mismatches that can't be used for looking at the summary statistics of the output parameter distributions.
