PySide/PyQt Zarr hierarchy tree model-view widget

[marcel-goldschen-ohm]

I've created a PySide/PyQt widget for viewing and editing a Zarr hierarchy at https://github.com/marcel-goldschen-ohm/zarr-view. The original idea was to provide a tool with similar functionality to HDFView. I'd be interested to hear what people think of it and what additional features you would like in it. Also, if anyone has any ideas on speeding up performance when loading a really large tree, that would be awesome.
