Recent commit broke state_reconstruction

Commit core.data.arrays.ArrayData: Add __array_function__ broke interplay with state_reconstruction.

The new function __array_function__(self, func, types, args, kwargs) throws an "AttributeError: 'list' object has no attribute 'shape'" when numpy.broadcast_arrays is cast in code cell [10] in psf+trafo_estimation.ipynb. The numpy function does indeed return a list of arrays instead of an array.

Tested using Python 3.11.5.
