Subject: I simplified the countdown, by moving it into it's own function
 instead of wrapped inside guided.. This can now be used by others for a
 simple countdown. I also re-worked the minimal.py example to work with the
 new internal partitioning logic API as well as support some flags from
 archinstall.arguments to minimize user input requirements to just one single
 question. This one question will most likely go away too, but stays for
 simplicity right now.
