metrics.py: fix compatibility with scipy >=1.13

[mattpitkin]

As of scipy v1.13, the hann window has been removed from scipy.signals and is now only accessible through scipy.signals.windows. This PR accounts for this move so that pyroomacoustics will work with the latest scipy versions.

Closes #342

• Are there docstrings ? Do they follow the numpydoc style ?
• Have you run the tests by doing nosetests or py.test at the root of the repo ?
• Have you checked that the doc builds properly and that any new file has been added to the repo ? How to do that is covered in the documentation.
• Is there a unit test for the proposed code modification ? If the PR addresses an issue, the test should make sure the issue is fixed.
• Last but not least, did you document the proposed change in the CHANGELOG file ? It should go under "Unreleased".

Happy PR 😃

Thank you for this fix. Using pyroomacoustics with the latest scipy is indeed broken.

Cool. Glad to be of help.

Just a quick note to say that the date for the new release in the changelog file needs to be updated!
