For directories with large numbers of files, figure out interface

[bmann]

For directories with large numbers of files, it takes a long time to load all of the files, and then it's not very useful.

Here's an example: https://drive.fission.codes/#/QmYGs1ksGX3eMiGvxNuvRT6PD7zPKZpHyiUDXKGQoL4R7S

This is a folder containing HLS encoded video files. If you scroll to the bottom, you get 410 Files (349.39 MB) as the summary.

We might want to only show XX files, and then implementing paging or lazy loading or search to filter down the total.

The summary of total files / size -- maybe even average / median file size could be interesting -- would be good at the top / in view.
