Unable to upload attachment as bytes - Solution

[dvrhax]

To start I'll say I'm ignorant of the pull request processor else I would have done this there.

My issue was is that I have a mmpy_bot that listens on MQTT and post messages. Recently I needed to upload an image instead of just text and as that image comes over as bytes already, I didn't want to save it and reupload it.

So I added this function to driver.py:

def upload_file_bytes(self, name: str, file_bytes: bytes, channel_id: str):
        file_list = [
            (
                "files",
                (
                    name,
                    file_bytes,
                ),
            )
        ]
        result = self.files.upload_file(
            files=file_list, data={"channel_id": channel_id}
        )
        print(result)
        return [info["id"] for info in result["file_infos"]][0]

*Without the print this doesn't return, so not sure what race condition is going on

I then also modified create_post with this parameter declaration

file_ids: Optional[Sequence[str]] = None

and then added a conditional around the file_ids creation in the body

if file_paths:
            file_ids = (
                self.upload_files(file_paths, channel_id) if len(file_paths) > 0 else []
            )

Let me know if there is something I'm missing and there's a better way to do this or if I can help in some other way. Would appreciate this getting merged so that I can continue to stay up to date, or I can always fork.

Thank you
