ZSO-Files should not be compressed again

[Gunnar-GO]

If you try to transfer the ps2-games-zso, allready compressed by OPL-Manager 22.1, the script shouldn't generate an new zso and transfer this new file.

It should be checked if the file is allready optimised.

They are already checking if it exists but according to current logic it needs the original iso to be able to install the ZSO because it needs to get information from the iso

So it extracts the ZSO to get the iso then it transfers the ZSO
