An issue (maybe?) with FileUploader

[igor-alexandrov]

Hey! I got a problem with Shrine (https://github.com/jetrockets/shrine.cr). In some cases (one of our applications that worked with 0.35 before and new Shrine specs), we are getting an error that is below. Maybe it is not really problem of FileUploader, but for sure not all subclasses of IO respond to size.

Do you have any ideas how this can be solved?

In src/shrine/storage/s3.cr:57:18
