SpatialData example based on the `codex-2023` example configuration on vitessce.io

[keller-mark]

We should create a jupyter notebook which reproduces the example from https://vitessce.io/#?dataset=codex-2023 but stores the data in a SpatialData object.

Similar to https://github.com/vitessce/vitessce-python/blob/main/docs/notebooks/spatial_data_kpmp_vis.ipynb for the corresponding kpmp-2023 example
