Large-scale refactor of Nix flake.
151b4f7 
- Fixes the Nix build by removing the absolute path to Bash.

- Changes packages to be named "name/target" instead of "name-target"
  - Target names also have hyphens in them, so parsing them is a bit of
    a pain.

- Removes aliases for components of the image. These are still exposed
  as passthru attributes, but they don't have the target name in them
  any more. This should be more consistent and simpler to program around.

- Uses a "g" prefix for non-release versions instead of another
  hyphenated component. This again reduces ambiguity in parsing paths.

- Adds flake checks that all the ukoOS builds succeed and all the image
  builds succeed, and runs these checks in GitHub Actions.

- Prepares GitHub Actions to be used with other image targets (e.g. #56).
  This is done through the all-images package; whatever files that
  builds will get uploaded as artifacts.

- Fixes the REUSE tool being added as a dependency of ukoos instead of
  as a devShell input.

Loading

Notes for testing:

Setup:
Attach UART pins to CPU UART, not security chip UART thing

build:
nix build -L .#all-images

flash src/result/dev-image-milkv-jupiter.img to microSD card

serial into the board

Need to see what u-boot is doing (it's loading GRUB?)

pins to reset/ignore SPI flash, since u-boot is being loaded form SPI flash?

CHANGES:

The commit after this will be updating the memory addresses in code to match that of the Jupiter, which is a temporary fix, and this should not be merged with those changes.
It also fixes the u-boot.txt file with more configs for the Jupiter.

TESTING:

Go to the ukoOS u-boot repo, use commit ed29515c8baed05cdc1284474a847df214b0383c from the spacemit-k1-testing branch, copy the src/image-milkv-jupiter/u-boot.txt from this Pull Request into the board/spacemit/k1-x/k1-x.env, then to build:
nix build --override-input u-boot-spacemit-k1 ../ukoos-uboot/ -L .#all-images

@Owen-sz
Align to Jupiter hardware
63fe92e 
Correct Jupiter nix file to load kernel into correct spot
Add /boot into Jupiter genimage.cfg
Update u-boot.txt with Jupiter things, and set new startaddr because the Jupiter's RAM is not the same place as the Duo S and QEMU
Update files that rg told me had the Duo S/QEMU staraddr to temporarily to include the Jupiters startaddr
