Let’s say I found a really old version of NodeJS on nixpkgs and I have the pinned nixpkgs commit for it. Is there a way to include a package from that pinned nixpkg in a flox environment?

Context: I’m coming from a nix background, don’t know much Flox terminology (e.g. catalog), but do at least know there’s a flox fork nixpkgs that maybe includes stuff like the ld-floxlib to make things work.

we’re currently working on [broadening the software available](https://github.com/flox/flox/issues/1197) in Flox but don’t yet support installations from a specific revision. will be something we add soon to support grabbing older versions of things like nodejs.
