xcube multilevel datasets cannot be investigated with python api

[AliceBalfanz]

Describe the bug
When opening a .levels data with xcube, it cannot be checked with xrlint:

The same dataset can be investigated using the cli command without problems.

To Reproduce
Try inspecting .levles dataset which is opened via an xcube store.

Expected behavior
I would expect the same behaviour as when using the cli tool.

Python Environment

• operating system:
• XRLint version, output of xrlint --version: 0.5.1
• optional: packages and their versions, output of pip list or conda list:
• xcube 1.12.0

Additional context
From chat with forman: "da wird zu früh geprüft, ob das dataset-Argument ein xr.Dataset oder xr.DataTree ist und daher kommt kein Plugin zum Zuge, d.h., das xcube Plugin bekommt ein MultiLevelDataset nie zu sehen."

Thanks for reporting @AliceBalfanz!

I only had little time lately, but still hope to address your issue in December!
