Seems to work perfectly, but I'm making a small suggestion

@nicolaskempf57 We remove the api.representation line for media. The whole APIv2 was passing through it.
Instead we use the get argument to know which header to include in the response. Does it look okey to you?

Yes ! This was done because the captcha calls doesn't include any Accept header so flask-rest-x treats it as application/json and that prevent it for sending the response as bytes.
