-#63: Add `config.haskellProjects.${name}.outputs` containing all flake outputs for that project.
- API changes
-#37: Group `buildTools` (renamed to `tools`), `hlsCheck` and `hlintCheck` under the `devShell` submodule option; and allow disabling them all using `devShell.enable = false;` (useful if you want haskell-flake to produce just the package outputs).
-#52: Expose the final package set as `finalPackages`. Rename `haskellPackages`, accordingly, to `basePackages`. Overlays are applied on top of `basePackage` -- using `source-overrides`, `overrides`, `packages` in that order -- to produce `finalPackages`.
