def dask_map_with_progress[T, R, **P](

a progress bar is used that is updated every 100ms. For computation that takes >10minutes that is a lot of printing to the stderr.

With tqdm progress bar we can set TQDM_MININTERVAL env var, to print less often. It would be nice for the dask progress bar to have something similar.
