Crash: missing import in datasets/utils.py

[mmjamm]

It seems one of the URLs for the built-in SOFA files has gone bad and reveals a bug in the code.

from pyroomacoustics.directivities import MeasuredDirectivityFile

if __name__=='__main__':

    hrtf = MeasuredDirectivityFile(
        path="mit_kemar_normal_pinna.sofa",  # SOFA file is in the database
        fs=24000,
        interp_order=12,
        interp_n_points=1000
    )
    print(hrtf)

When I run the above code, I'm getting the following error:

File "/home/build/.local/share/virtualenvs/pra_dir_test-S0HkAUoS/lib/python3.11/site-packages/pyroomacoustics/datasets/utils.py", line 132, in download_multiple
    except URLError:
           ^^^^^^^^
NameError: name 'URLError' is not defined. Did you mean: 'EOFError'?

This can be fixed by adding from urllib.error import URLError to the beginning of the file.

My guess is that this hasn't been visible before, and now one of the links (https://fedora.kug.ac.at/fedora/objects/o:68229/methods/bdef:Container/get?param0=LSPs_HATS_GuitarCabinets_Akustikmessplatz.sofa) has gone stale and shows the bug.

Python version used: 3.11.8

Thanks for the fix. This error occurs even if you are locally loading a sofa file.
