see https://docs.aws.amazon.com/AmazonS3/latest/userguide/mpuoverview.html#distributedmpupload
for multipart upload version_id order should be determined by creation time rather than completion time as we do today
Describe the solution you'd like
instead of putting always the new upload as the latest version we need to -
Set the mtime of the composed file to be the creation time of the multipart upload file or put the timestamp inside the file
Check the latest version mtime and compare it to the mtime of the init mpu and decide if to put it as the latest version or inside .versions/
