Fix handling of gzip-encoded text response

[suriya]

Description

When Zappa receives a compressed text/plain response from the
application, it tries to process it as a text response. Instead, Zappa
should treat the response as if it were a binary one and base-64 encode
the response body.

Just need to look at the 'Content-Encoding' header on the werkzeug response. If it's present, then just base64 encode the response as normal.

This logic here:

                        if (
                            settings.BINARY_SUPPORT
                            and not response.mimetype.startswith("text/")
                            and response.mimetype != "application/json"
                        ):

Replace it with this

                        if (
                            response.headers.get("Content-Encoding") or
                            (settings.BINARY_SUPPORT
                            and not response.mimetype.startswith("text/")
                            and response.mimetype != "application/json")
                        ):

Edit

Sorry if this wasn't clear. Your PR looks like it should work. I was just suggesting that it could be restructured so there isn't duplicated code blocks.
