dscim tests seem to fail when using zarr >= v3.x package

[brews]

dscim directly depends on the zarr package. When dependabot tried to bump the zarr-python package to the new v3.0.0 release, it failed CI checks.

See the PR here: #368

Cut-n-pasted from CI logs:

==================================== ERRORS ====================================
_________________ ERROR collecting tests/test_input_damages.py _________________
ImportError while importing test module '/home/runner/work/dscim/dscim/tests/test_input_damages.py'.
Hint: make sure your test modules/packages have valid Python names.
Traceback:

From a quick look it looks like it's failing to even collect test_input_damages.py because it's importing something that's now missing from the zarr package in this input_damages.py
