binary cache of nix store artifacts

[mazunki]

I have set up a nix cache at https://nix-cache.mazunki.tech. I've built both ec759bd and 02a3996 on it.

Usage is fairly trivial if one is on a NixOS machine:

# /etc/nixos/configuration.nix
  nix.settings = {
    substituters = [ "https://nix-cache.mazunki.tech" ];
    trusted-public-keys = [ "nix-cache.mazunki.tech:g+E2FKZXvJ92hQGUKRTRuul32JtHUmT/QGYR6W4Z1gE=" ];
  };

I'm not sure one can add binary caches into nix2 declarations. I know flakes supports it, but for now it seems like adding it to configuration.nix (or alternatively /etc/nix/nix.conf) is probably the best. Should we merge a list of binary caches into the repo itself, or should we keep this information standalone?
