Support for chunk uploading

What is the problem you are facing?

I just got hit by Cloudflare 100MB upload limit when I was attempting to upload a 164MB file. And it would be nice if Funkwhale were to support chunk uploading for those users who maybe using a CDN in front if their instance.

What are the possible drawbacks or issues with the requested changes?

If the complexity is too difficult or unnecessary change for such small files. Feel free to close this issue. I'll simply find a work around.

Context

This may or may not help for unstable connections? Possibly a resume feature? Again for such small files, this might be too of a low priority.
