dependency on an old scipy version

[g-puleo]

Hi.
It looks like line 5 of this file is

from scipy.integrate import simps

which raises the following ImportError upon importing swyft (i was able to reproduce this error both with swyft==0.4.4 and 0.4.5 installed via pip).

>>> import swyft
Traceback (most recent call last):
  File "<python-input-0>", line 1, in <module>
    import swyft
  File "/home/giammi/miniconda3/envs/empty/lib/python3.13/site-packages/swyft/__init__.py", line 1, in <module>

    )
  File "/home/giammi/miniconda3/envs/empty/lib/python3.13/site-packages/swyft/plot/plot.py", line 5, in <module>
    from scipy.integrate import simps
ImportError: cannot import name 'simps' from 'scipy.integrate' (/home/giammi/miniconda3/envs/empty/lib/python3.13/site-packages/scipy/integrate/__init__.py)
>>> 

The simps function was present up to scipy 1.5.4 and was later renamed to simpson, but the requirements only enforce scipy>=1.4.1, which allowed my pip to install scipy==1.16.0. I believe the easiest solution is to update the function name in the swyft source code.

I hope this is helpful :)

Dear @g-puleo, thanks a lot for opening this issue!

We are not actively developing swyft anymore (there is a new framework in the making), but I will put this bug fix on the todo list.

Best regards,
Christoph
