[BUG] Tests fail with NumPy 2.2.0 #1499
Description
Fedora has recently upgraded NumPy to 2.2.0 in the development branch. Building meshio with that version results in a number of tests failing:

============ 25 failed, 714 passed, 6 skipped, 25 warnings in 4.68s ============The set of errors is:
ValueError: could not convert string to float: 'np.float64(63.69616873214543)'
ValueError: cannot reshape array of size 1 into shape (4,2)
meshio._exceptions.ReadError: Header of ugrid file is ill-formedThe full log of all test failures is too big to post here. But this should be rather easy to reproduce in a venv. On my Fedora box I'd do:
python3.13 -m venv .venv
. .venv/bin/activate
pip installe -e .
pip install pytest netCDF4 h5py
pytest -v
For a quick glance, the log from the latest build attempt is accessible online:

It will be cleaned up over time, however.
