idea: provide slide for people who share data or reuse data on DANDI

We want people to talk about the data they share and reuse on DANDI. Let's make that as easy as possible for them. The idea is to automatically generate a slide that is shared CC-0 and can be used by anyone who shares or reuses data. It could have info like:

* Dandiset name, description, DOI
* Basic dataset stats (standard used, size, date, types of data, etc.)
* Links to data interfaces (DLP, Neurosift, dandi-atlas, etc.)
* Code to download data
* Info about DANDI

I'm not exactly sure how this would be shared with the user. Any ideas? Do we think people would actually use this in their talks?

Start by reviewing how DANDI currently presents dandiset metadata and how users access shared or reused data. Define the delivery mechanism and confirm that the generated CC-0 slide includes the listed metadata, dataset statistics, interface links, download code, and DANDI information.
