Transloadit Performance Test

Build a super basic transloadit direct upload test in order to compare upload times using transloadit vs using AWS directly.

Steps:

Maybe just do this directly in as-file-upload? Instead of getting a signature for now just use a hardcoded transloadit secret.

Setup a transloadit assembly that just saves to S3. Maybe it handles the image rotation too, but we can worry about that later. For now we just want to compare the upload speeds and see if they compare favorably.
