The `slice_along_path` function has been added to `analysis.interpolate`, which enables easy interpolation along a evenly spaced path that is specified by its vertices and step size. The path can have an arbitrary number of dimensions and points.

🐞 Bug Fixes

- **io:** remove direct display call in interactive summary ([d44b3a5](https://github.com/kmnhan/erlabpy/commit/d44b3a56aecfb054a38d944c5c8b7f45d362cf3b))
