Feature request: unzip archives on server

**is your feature request related to a problem? Please describe.**
I'd like to use cpp to access zipped archives of backups and unzip them on the server, instead of downloading the archive and uploading the unzipped one again.

**Describe the idea / solution you'd like**
Ability to unzip an archive

**Describe any alternatives you've considered**
download - unzip - upload

Thanks for considering!
