Build nix packages from source (#253)

* nix: get source tarball with update.py

* nix: build from source

nix: remove u2c and partyfuse packages
The main copyparty package has u2c and partyfuse, so these packages are
redundant now

nix: add fusepy dependency

fix: nix:  use replace pyfuse with fusepy

* nix: fix extra python packages

* nix: add optional dependencies

* nix: add partftpy package

* nix: add tftp parameter to package

* nix: enable pyproject for partftpy package

* nix: replace partftpy overlay with real package

* nix: add updater for partftpy

* nix: bring back local release pin to update.py

nix: update local release pin function in update.py
