Binary audio uploads for transcription and translation capped at 80 MB

Direct (binary) audio uploads for transcription and translation are now capped at 80 MB per request. For larger files, host the audio at a public HTTPS URL and pass that URL as the file field, which supports up to 1 GB. When sending a binary upload, place the model form field before the file field in the multipart body.

See Transcribe audio for details.
