more information about each dataset

## Use Case

Contact information, how to download the data, a general manifest of the contents of the dataset, extended info about publications methods and analysis code etc.
Example: https://open.quiltdata.com/b/allencell/tree/aics/label-free-imaging-collection/README.md

## Solution

I believe this could be a third tab in the app: "Plot", "3D Viewer", "Dataset Info". But however users access it, providing a way to give extended explanatory information about a dataset from within the CFE app would be nice.
