In the FTPSHook it's also possible to pass a buffer (like StringIO/BytesIO) instead of a path, I've refactored the retrieve_file and store_file methods in SFTPHook so those also support those types. This avoids the need to create a file to be able to download a file to FTP, you can directly download it into a buffer and vice versa if you need to upload content to an FTP server you don't need to create a file locally to be able to upload it. I just delegate this to the underlying paramiko getfo and putfo methods, nothing fancy had to be done to achieve this as the paramiko library already supported this. This shortcoming was described as a pitfall for the SFTPHook.
