[Python3] Binary decode fails

[POD666]

Description

I'm using openapitools/openapi-generator-cli:v3.3.1 docker image to generate client from my swagger.yml

One of endpoints returns binary data and generated client fails with UnicodeDecodeError.

The problem is here. I don't need response to be decoded to string as it's binary file.

My workaround is to pass _preload_content=False to the api call and handle urllib response object by myself.

I can suggest to simply wrap .decode("utf-8") in try-except.

@POD666 thanks for reporting the issue. Do you mind filing a PR with the suggested fix so that we can review more easily?

Probably we should remove attempt to decode data at all as it's saved as binary any way.
Or try to decode elsewhere, e.g. here.

Receiving binary data now works in the python client.
