restructure repository as a cargo workspace

This restructures the repository as a cargo workspace with two crates:

- galileo-osnma, which contains the library and all the binaries
  that run on a host PC, including helpers that were previously in
  their own crate.

- osnman-longan-nano, which contains the longan nano firmware.

Additionally, just has been added as a command runner and the
Github CI has been refactored.
