An attempt at enabling the fuellabs nix cache via the flake's `nixConfig` attribute. The idea is to hopefully remove the need for adding cache info to the user's global config and ease usage slightly. From `nix help flake`: > nixConfig: a set of nix.conf options to be set when evaluating any > part of a flake.

Currently this doesn't seem to be working - I'm running into the same issue described here NixOS/nix#6672. Either the user has to be part of the "trusted-users" set (i.e. is allowed to specify new substituters) or the fuellabs cache already has to be part of the global `trusted-substituters` list, otherwise the fuellabs cache is ignored.

I raised the issues around exposing a nice UX over a custom Nix cache in this forum post: It appears there is no immediate nice solution, but that in the long run the new CA (content-addressed) derivations feature should remove the need for trusting substituters at all. |

Closing in favour of the new installation approach in the book https://github.com/FuelLabs/fuel.nix/blob/baf2162a5b28fede20d3cc03e68eca006265c413/book/src/quick-start.md. |

nixConfigalso allows you to specify the required "nix-command" and "flakes"experimental-features. However, you already need to have these features to even start using the flake, so I've omitted them from the config as the user should always already have them.
