[ENH] - Allow multiple file uploads in a single POST request

[sccolbert]

Feature description

as it says on the tin...

Maybe update POST /files to take an array of file data instead of just a single, then return an array in kind.

Value and/or benefit

This would eliminate await calls in a loop on the frontend when the user is trying to attach multiple files to a single prompt.

Anything else?

I'm in favor of this in general, but I need to do research of how large JSON blobs will be delivered. I'm only familiar with multipart requests for large uploads.
