Adding the Neuroglancer button
Test to integrate a button in the dataset page to view it with Neuroglancer. For now, the information needed for Neuroglancer is extracted from a local JSON file but I try to mimick as much as possible the code structure for the incoming API calls through IDS
It seems to work correctly, however, I am uncertain of the way I do it. It seems really heavy to me the way I did but I don't know how to do it differently
