Personal / private leaderboards/ dashboards

[yamins81]

It would be nice to have a “private configurable leaderboard”--e.g. some way for a user to see their private models (as well as other models of their choosing drawn from the larger set of public models), but in a kind of the same way as the public models are shown, with a ranking leaderboard and also the ability to do scatters.

It should be nicely enough set up to allow people to make near-publication-ready figures (or for, say, tweets). I think this would incentivize people to use brain-score in their own research more.

This issue is related to #256 in that it is about improving the UI/UX for users to get satisfying presentable research-level outcomes from their submissions to brain-score.
