i believe until #98538 is merged, our kicad can't work on darwin

there's still a comment in default.nix calling out libngspice as linux only, but that has been fixed
i don't have a way of confirming that issue is actually resolved though

ah yes, the traditional PR merge as i find an issue and start working on it :D

3D models in kicad-unstable don't work (this issue is not introduced in this PR)
the packages3d install path changed, to adjust this:
under preferences -> configure paths, change KISYS3DMOD from
kicad-packages3d-2020-12-23/share/kicad/modules/packages3d/
to
kicad-packages3d-2020-12-23/share/kicad/3dmodels/
(s/modules\/packages3d/3dmodels/)
a popup should warn you that this change is temporary, you'll have to re-do it every time you start kicad
or modify the package to use the new path in the wrapper
the newest kicad source has more advanced issues with 3D model paths (open issue) which i'm waiting to be resolved before opening a PR
