PointsModel warning

[dariotommasini]

Hello!

I got this warning when running:

sdata = sdio.xenium(
    "/path/to/my/folder",
    nucleus_boundaries=False,
    cells_boundaries=False,
)

WARNING  The `feature_key` column feature_name is categorical with unknown categories. Please ensure the categories
         are known before calling `PointsModel.parse()` to avoid significant performance implications due to the   
         need for dask to compute the categories. If you did not use PointsModel.parse() explicitly in your code   
         (e.g. this message is coming from a reader in `spatialdata_io`), please report this finding.

It said to report this finding.

Thank you!
