pesummary accesses protected variable from tqdm

I've just noticed (after a job failed) that pesummary accesses a protected variable from tqdm at https://git.ligo.org/lscsoft/pesummary/-/blob/master/pesummary/utils/utils.py#L28.

This works with the latest version of the code, but not with an (admittedly much) older version I was running.

It also looks like this is done to support python 2, which pesummary doesn't do.

Please can we remove this from the code, as I suspect it will be unceremoniously removed from tqdm in some future release?

This was the traceback
