This package is not affected by the breaking changes in NumPy 2.0.

When running all of the tests cases with NumPy 2.0.0rc1, the image
"doc/getting-started/lorenz63_forecast_regularised.png" was slightly
different; the y-axis line extended one pixel higher than previously,
and several surrounding pixels differ slightly (due to antialiasing).
The modified image is not included in this commit.
