* Add flake.variants This allows flakes to easily include variations of the project by with different project arguments. Anything you can pass to `project.addModule` can be used. For instance to include variants using ghc 9.2.4: ``` flake.variants.ghc924.compiler-nix-name = pkgs.lib.mkForce "ghc924"; ``` Then use it with: ``` nix build .#ghc924:hello:exe:hello ``` This change also: * Exposes add `combineFlakes` and `rawFlake` for more control over how flakes are combined. * Includes package coverageReports to the `hydraJobs` of the flakes. * Tries to make the materialisation concurrency test more reliable
