When a large file is requested the contents returned is malformed. This appears to be a bug in PHP and relative to its default chunk size of 8192. The first chunk seems to be repeated.
In order to address this we can store the contents of the file returned from the SFTP client's get method into memory and return the resource for that. I've also added in an additional option for storing the file locally in the event of the remote file not being able to be fetched. In either case we're no longer directly streaming the file using the sftp protocol.
