Shows which data sets exist but not the contents or attributes

All I see is which data sets exist but not contents, attributes, or contents of the attributes. I'd really like to be able to see that for smaller HDF5 files at least. I'm willing to help contribute if that would be helpful

Sorry for the late response.
Feel free to create a PR.

To be honest I had some issues using other libraries than the pure JavaScript based.
Unfortunately that one does not fully support the format.
But the attributes should be visible 🤔
