Slashes in .h5 paths are converted to escaped backslashes

[cjstephen]

Describe the bug

Trying to inspect an h5 file with tree structure "/confocal/XY/...something.../raw". On initially opening in h5web under jupyter, left pane shows "/confocal" but opening this gives a blank plane.

Digging into the errors I found the following which seems to suggest the second slash is converted to '\\'

{"message": "Unhandled error", "reason": null, "traceback": "Traceback (most recent call last):\n File "C:\Users\u1774090\Anaconda3\envs\h5web\lib\site-packages\tornado\web.py", line 1702, in _execute\n result = method(*self.path_args, **self.path_kwargs)\n File "C:\Users\u1774090\Anaconda3\envs\h5web\lib\site-packages\tornado\web.py", line 3173, in wrapper\n return method(self, *args, **kwargs)\n File "C:\Users\u1774090\Anaconda3\envs\h5web\lib\site-packages\jupyterlab_h5web\handlers.py", line 26, in get\n content = self.get_content(h5file, path)\n File "C:\Users\u1774090\Anaconda3\envs\h5web\lib\site-packages\jupyterlab_h5web\handlers.py", line 59, in get_content\n return content.metadata()\n File "C:\Users\u1774090\Anaconda3\envs\h5web\lib\site-packages\h5grove\content.py", line 151, in metadata\n ("children", self._get_child_metadata_content(depth - 1)),\n File "C:\Users\u1774090\Anaconda3\envs\h5web\lib\site-packages\h5grove\content.py", line 139, in _get_child_metadata_content\n return [\n File "C:\Users\u1774090\Anaconda3\envs\h5web\lib\site-packages\h5grove\content.py", line 140, in \n create_content(self._h5file, os.path.join(self._path, child_path)).metadata(\n File "C:\Users\u1774090\Anaconda3\envs\h5web\lib\site-packages\h5grove\content.py", line 160, in create_content\n entity = get_entity_from_file(h5file, path, resolve_links)\n File "C:\Users\u1774090\Anaconda3\envs\h5web\lib\site-packages\h5grove\utils.py", line 34, in get_entity_from_file\n raise PathError(f"{path} is not a valid path in {basename(h5file.filename)}")\nh5grove.utils.PathError: /confocal\\XY is not a valid path in session-20211021-131238.hdf5\n"}

Expected behaviour

Should allow traversal of an h5 tree from root

Thanks for the report ! This should be fixed in jupyterlab-h5web's latest version (0.0.11)
