[Feature/Bug] Amazon S3

[bemanuel]

When the target is a directory, S3 sync just copies the directory name and forget its content. Maybe I'm doing some mistake? I'm using PHP7.2 / PHPBU 6.0.15 -> PGDump -> useMultiPartUpload

Maybe if I implement tar compression for it, could be better than upload a directory full of different files from the same dump. I was thinking of tar because sometimes, like a pgdump directory, the process still compresses the files and using tar to avoid unnecessary usage of CPU.
