What's Changed
* adjust to xarray datatree by melonora in https://github.com/spatial-image/multiscale-spatial-image/pull/94
The library `datatree` has been archived. `Xarray` now includes `DataTree` directly. Some changes to the datamodel have been made. In short dimensions and indexes in child nodes should exactly align with those in their parents. However, for `MultiscaleSpatialImage` this does not seem to be the case as the root node does not contain dimensions while the child nodes do. According to [migration guide](https://github.com/pydata/xarray/blob/main/DATATREE_MIGRATION_GUIDE.md) the dimensions and indexes of sibling nodes do not have to align.
On top of these changes the `DataTree` has certain methods removed. The behaviour of these methods can be replicated (in particular when adjusting dimensions or reindexing) by writing a decorator that takes a `xr.Dataset` and skips over the nodes that contain `dims` of length `0`. One can then apply `map_over_datasets`. For documentation, see [here](https://docs.xarray.dev/en/latest/generated/[xarray.DataTree.map_over_datasets](https://docs.xarray.dev/en/latest/generated/xarray.DataTree.map_over_datasets.html).html).
