coast.transect: scipy.integrate.cumtrapz deprecated

[jdconey]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Since scipy 1.14, integrate.cumtrapz has been removed in favour of integrate.cumulative_trapezoid. This is causing coast to fail to import when the latest versions of scipy are installed.

From my quick look at things, changing the transect script to import this new description should fix this behaviour.

Expected Behavior

import coast should have run without error.

Steps To Reproduce

1. With a newish version of scipy installed (1.14 or later):
   import coast

Environment

- OS: Jasmin sci machine (system='Linux', node='sci-vm-01.jasmin.ac.uk', release='5.14.0-503.21.1.el9_5.x86_64', version='#1 SMP PREEMPT_DYNAMIC Wed Jan 8 17:35:30 UTC 2025', machine='x86_64')
- python: 3.10.2

Anything else?

Yes, replacing the implementations of integrate.cumptrapz to integrate.cumlative_trapezoid fixed this issue. I will create a branch and merge into develop
