Imagedata

* Fixed viewing in jupyter notebook using backend `widget`.

* Renamed collections.py to collection.py.

* Support python 3.13.

* Series: Axes property implementation is changed from a list to a namedtuple.

* Series.__get_tags(): Corrected looping over slice objects.

* Series: Let __array_function__ call numpy for functions we do not implement.
This will possibly return an ndarray instance, not a Series instance.
* Axis: Added property `values` which will give all axis values.
* DICOMPlugin.write_slice(): Added parameter tag_value which gives the tag value
instead of relying on tags property.
* Series.concatenate(): Corrected behaviour.
