Personal binary cache for Nix

[kachick]

Using flake or patched and/or unfree packages. Cannot be used in official binary caches.
Especially for wezterm, wezterm often require nightly, but it takes long time to build.

How about https://github.com/zhaofengli/attic. https://github.com/cachix looks like providing expensive plans for personal use...

ref: #472, #679

macos-13 runner now takes about 20 minutes, when ubuntu takes 3 minutes

Required for several packages. In unfree packages, they does not have binary cache in cachix

Since #882 and https://github.com/kachick/dotfiles/pull/861/files#diff-206b9ce276ab5971a2489d75eb1b12999d4bf3843b7988cbe8d687cfde61dea0R201

Or use https://github.com/numtide/nixpkgs-unfree?

https://discourse.nixos.org/t/petition-to-build-and-cache-unfree-packages-on-cache-nixos-org/17440/26

Or replace vscode with vscodium?
And Replace signal with something?
