Fix: Large number of dataframe columns (H5py Attr Limit)
Hi @ivirshup @brainfo,
This PR solves https://github.com/scverse/anndata/issues/874. I had a chat with h5py people and this was the simplest workaround they recommended. They also have no idea why it works. See https://github.com/h5py/h5py/pull/2311#issuecomment-1734102238.
Done:
- [x] Closes #874
- [x] Tests added
- [ ] Release note added (or unnecessary)
