Feature request: pre-generated indexes for main Nixpkgs channels/flakes

[jlbribeiro]

Again, thank you for open-sourcing rippkgs.

Would you consider providing pre-generated rippkgs indexes for the main Nixpkgs channels/flakes (latest NixOS stable release + nixpkgs-unstable, maybe?), similar to nix-index-database for nix-index?
