I removed my split.sh and integrated .bash_aliases into pack_and_send.sh.

I further changed pack_and_send.sh so it can be used similarly like get_dataset.sh.

I did not use lz4 because it is only a compression and not a packaging tool.

One still would have to use tar or another packaging tool in combination with it.

Unfortunately, I did not find a way to decompress a single huge .tar file (e.g. ~770GB) using multiple CPUs/processes.
