Converting openst adata object to SpatialData sdata object

[Aeget1000]

Feature Description

It could be very useful if there were an openst function which converts the 'stitched_spots.h5ad' into a SpatialData object.

Use Case

This would allow for easy transfer to the Sopa framework and would allow users to test some of the transcript-based segmentation found here.

Proposed Implementation

I have been trying out "from spatialdata_io.experimental import from_legacy_anndata" but you have to do some data wrangling for it to accept the openst adata format.
