Rationale of this change
As recommended by the SPEC (Scientific Python Ecosystem Coordination), and as communicated in this announcement, the Power Grid Model has been scheduled to drop support for NumPy 1.x on 1-Oct-2025 (see also SPEC 0's drop schedule for 2025-Q3).
Consequences of this change
Starting with the release associated with this PR, newer releases of power-grid-model and dependent libraries (power-grid-model-io and power-grid-model-ds) will no longer have active backwards compatibility for NumPy 1.x. In particular, we may do a change that breaks compatibility with NumPy 1.x at any date after the active support is dropped. Please upgrade to NumPy 2.x as soon as possible to stay up to date with new features, as well as important security updates and bug fixes.
