Files list slow to render when directory contains many files

[olizilla]

We're need to paginate the rendering of large directories. We're using react-virtualized for the peers list and the links list in the ipld-explorer, so it'd make sense to use that here.

To deal with really large directories of things, we'd also need to be able to request paginated chunks of a dir listing from the api.

We did it good if...

• Files page can render the (first few) files list for a directory containing > 1000 files in < 1s

I can only find an issue with requesting paginated chunks from the API: it must also support sorting otherwise the user experience will be a mess.

It's still slow if the webui is hosting on a remote server.
May the file list load the stat of files in parallel using Promise.all() instead of one by one? Or just lazy load the CumulativeSize of them because the size is sometimes not the most important thing.
