[MAINT] Numpy 2.5 deprecation warnings caused by netCDF4

[hoyer-a]

Deprecations in numpy 2.5 are causing deprecation warnings in write_sofa and read_sofa, this also affects the pyfar tests (pyfar/pyfar#943).
Not sure if we can fix this in our code or if this is an issue with netCDF4.

Warning:

...
sofar/io.py:256: in write_sofa
_write_sofa(filename, sofa, compression, verify=True)
sofar/io.py:331: in _write_sofa
tmp_var[:] = value
^^^^^^^^^^

E DeprecationWarning: Setting the shape on a NumPy array has been deprecated in NumPy 2.5.
E As an alternative, you can create a new view using np.reshape (with copy=False if needed).

Looks like this might be an issue with how the python wrapper for netCDF implements slicing. Or what type is tmp_var?

[hoyer-a]

Yes, it's a netCDF4.Variable

Should be fixed with next netCDF4 release
