[BUG] Numpy 2.x not supported

Describe the bug python-picamera2 does not import when using numpy 2.x

To Reproduce Ensure latest picamera2 python system package is installed as well as numpy 1.26.4 or older (1.24.2 seems to be the system package version)

$ apt list python3-picamera2
python3-picamera2/stable,stable,now 0.3.19-1 all [installed]
$ python3 -m venv --system-site-packages .venv
$ source .venv/bin/activate
$ pip freeze |grep -E 'numpy|picamera|scipy'
numpy==1.24.2
picamera2==0.3.19
scipy==1.10.1

Validate import works with numpy 1.x

$ python3 -c 'from picamera2 import Picamera2' && echo $?
0

Upgrade numpy to latest 2.x (and scipy, requires newer)

$ pip install numpy==2.0.1 scipy==1.14.0
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Collecting numpy==2.0.1

Collecting scipy==1.14.0

Successfully installed numpy-2.0.1 scipy-1.14.0

Import picamera2 and see that it fails

$ python3 -c 'from picamera2 import Picamera2' && echo $?

ValueError: numpy.dtype size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

Expected behavior Import should not fail with latest numpy
