Closes #27

### Description - Updated `nix.conf`, some settings we're [renamed](https://github.com/NixOS/nix/blob/60936f28e51bad1cf0a038ebfa24ce9bb97845a9/doc/manual/src/release-notes/rl-2.0.md?plain=1#L394-L398) for `nix 2.0+`: - build-max-jobs -> updated to `max-jobs` - build-cores -> updated to `cores` (value "0" is default and a [special value to use all CPU cores](https://github.com/NixOS/nixpkgs/blob/9ab019d53ad1dba59311e5e33fecef22d445df2d/nixos/modules/config/nix.nix#L205)) - build-use-sandbox -> updated to `sandbox` - build-sandbox-paths -> updated to `extra-sandbox-paths` - added [auto-optimise-store](https://github.com/NixOS/nixpkgs/blob/9ab019d53ad1dba59311e5e33fecef22d445df2d/nixos/modules/config/nix.nix#L191) - added [trusted-users](https://github.com/NixOS/nixpkgs/blob/9ab019d53ad1dba59311e5e33fecef22d445df2d/nixos/modules/config/nix.nix#L296C13-L296C26) - added `substituters` - NOTE: currently armv7l binary cache is not yet officially supported by NixOS, that's why `cache.nixos.org` is not working and will just build the packages by cross-compiling. However, there is an [unofficial armv7l binary cache](https://hydra.armv7l.xyz/) that is supported by Nix users and is built in hydra, also documented here: https://nixos.wiki/wiki/NixOS_on_ARM#NixOS_installation_.26_configuration.
