python-packages: Add nixpart version 0.1.

This version is preliminary because it quite heavily depends on pykickstart
(through blivet) and the roadmap is to have a nice NixOS attrset-based
specification of partitions.

Currently the main purpose for this is in preparation for the Hetzner nixops
backend, but we might want to make this part of the standard NixOS installer.
