How to accept octet-stream

[dashesy]

I have the input sample:

input_sample = b"image_content"

Is there a way to accept binary content? I would like to send raw data (e.g. --data-binary of curl)

Instead of implicitely converting to base64, the schema should expect octet stream when input is bytes.
Option for octet-stream also makes it easier to use binary data and still use the automatic swagger generation.
