This release contains the `dataformat` module to:

- convert a Lagrangian dataset into a single class object `ragged_array` of contiguous ragged arrays;
- convert `ragged_array` objects into [`xarray.Dataset`](https://docs.xarray.dev/en/stable/generated/xarray.Dataset.html) objects and [Awkward Array](https://awkward-array.readthedocs.io/en/latest/index.html) [`ak.Array`](https://awkward-array.readthedocs.io/en/latest/_auto/ak.Array.html) objects;
- read in previously created archive.

In addition, this release contains a series of Jupyter Notebooks showcasing the functionalities of the library.
