Describe the bug
Following the simple installation guide, the base unit tests currently fail (for a single test). This is a simple roundoff error failure for test_local_exceedance_imp_pass.

FAILED test_impact.py::TestRPmatrix::test_local_exceedance_imp_pass - AssertionError: 2916964966.388227 != 2916964966.388219 within 5 places (8.106231689453125e-06 difference)

To Reproduce
Steps to reproduce the behavior/error:

1. mamba create -n climada_env -c conda-forge climada
2. mamba activate climada_env
3. python -m unittest climada.engine.test.test_impact

Expected behavior
Tests should pass!

Climada Version: 4.1.0

System Information (please complete the following information):

• Operating system and version: MacOS 14.5. M3 Max chip.
• Python version: 3.9.18

Additional context

• This issue shows up with the most barebones install of just climada. It persists with climada-petals installed.
• I tried uninstalling bottleneck but this didn't do the trick. I've found in the past that bottleneck can lead to roundoff level issues (bottleneck : Wrong mean for float32 array pydata/xarray#1346, Disable bottleneck by default? pydata/xarray#7344).
• Likely has to do with updates in versioning of numpy, xarray, bottleneck, etc.
