Feature Request: FilePicker indicate which files have already been uploaded

[j2d2]

Expected Behavior

When you open the Gallery it would be nice to see which files have already been added in prior sessions.

Current Behavior

You can select the same file multiple times and no UI to indicate that one was already done.

Possible Solution

We could pass an array of filenames to the picker in PickerOptions, if the UI would support indicating something on the thumbnail.
This solution would ideally work for all devices including desktops.

Context

Users are confused when uploading their videos from their phone - which ones have already been uploaded?

Your Environment

• Version used: "filestack-js": "^3.32.3"
• Browser Name and version: iOS Safari, Chrome (Webkit), Android, Desktop would be great too :)
• Operating System and version (desktop or mobile): mobile
