Update libzip aka Dependency management ...

git clone -b rel-1-5-1 https://github.com/nih-at/libzip.git

The used libzip is quite old and has seen some releases since the import - 1.11.1 as of writing this issue - see https://libzip.org/news/release-1.11.1.html

This raises some question on my end:

• Shall we update libzip?
• Are there any other dependencies? (I did not yet have a look at ios-sdk)
• What about using well known(?) dependency managers to keep things updated?

GitHub dependabot seems to only support Swift but not Cocoa or Cathage ...
