BinaryF is incorrectly represented as List[Boolean]

[elyast]

According to https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.0.3.md#encoding-object
" for string with format being binary – application/octet-stream " which would indicate the client method should allow to send stream of bytes (e.g. File as in other generators or Stream[Byte]), currently its being mapped to List[Boolean] which imho doesn't make sense.
