In looking at NZDir to try to figure out why the process_chunk combination was failing, I noticed that there are no test cases for NZDir. Strangely, codecov is just ignoring the file altogether, so it's not affecting the coverage report. There were tests of NZDir before it was moved to rail_sklearn, see https://github.com/LSSTDESC/rail_attic/blob/main/tests/estimation/test_nzestimators.py
Not sure why this test was not copied over.
[x] I have described the situation in which the bug arose, including what code was executed, information about my environment, and any applicable data others will need to reproduce the problem.
[ ] I have included available evidence of the unexpected behavior (including error messages, screenshots, and/or plots) as well as a descriprion of what I expected instead.
[ ] If I have a solution in mind, I have provided an explanation and/or pseudocode and/or task list.
