Support NeuroBagel annotation tool

This is essentially a client-side javascript annotation tool/workflow that produces a downloadable JSON object. In the future it will also support loading stored metadata.

The plan is to have a datalad extension that contains the JS blob and announces this metadata source to gooey via the envisioned entry point.

Thanks @mih, this sounds great. Right now we're working to get the annotator to output and load a JSON data dictionary - and in the process we're changing how the list of categories you can annotate are defined. Two things we could talk about in this context are:

1. The format of the data dictionary we're planning on creating and being able to load: define format for data dictionary output neurobagel/annotation_tool#220 The idea is that this format we use together with other metadata projects like dandi and repronim, and hopefully others
2. A format for a user createable config file that specifies the list of categories you'll see when you start the tool: define format for annotator config file neurobagel/annotation_tool#221
