Subject: [PATCH] default.nix: implement

This paves the way to hosting bitvend with NixOS.

Getting this to work required pulling in flask-oauthlib and a bunch of
older dependencies. This isn't great, but before we migrate
flask-spaceauth to use authlib that's what we have to do.

We also build pigpio/cygpio. pigpio should get upstreamed into nixpkgs.

We also rename bitvend.py to bitvend-run.py to unconfuse python paths.

To test:

    nix build
    result/bin/bitvend-run.py
