unknown method byte_size

[johan-smits]

I found already this issue (#44 ) but I'm using active storage in this case with a S3 back-end. So the proposed fix is not useful to me.

What I'm wanting to do is this:

property.asset.attach(io: Down.open("https://somedomain.tld/file.mp4"),
                      filename: "file.mp4",
                      content_type: "video/mp4")

So that it can read from the IO and stream the upload and download. Because it uses the S3 gem in backend it tries to read the byte_size to determine if it needs to use single part upload or multipart.

Would it be possible to provide a fix in this gem so that ActiveStorage will work to?
