OpenAPI importer sends format: binary octet-stream bodies as text/plain

A requestBody with application/octet-stream and format: binary goes out with Content-Type: text/plain. The octet-stream branch in generator.go checks the format against "bindary", so only format: byte gets the octet-stream header:

I parsed this spec with the openapi input format on dev (54f93109) and the POST /upload request came out with Content-Type: text/plain:

openapi: 3.0.0
info: {title: t, version: "1"}
servers: [{url: "http://example.com"}]
paths:
  /upload:
    post:
      requestBody:
        content:
          application/octet-stream: {schema: {type: string, format: binary}}
      responses:
        "200": {description: ok}

An upload endpoint that checks the content type might reject that, so it wouldn't get scanned with the body it expects.
