Add flake.nix and fix test that only passed in debug builds
Some checks failed
CI / build (push) Has been cancelled

- Add flake.nix with package (including examples) and dev shell
- Track Cargo.lock (removed from .gitignore) as required by the nix build
- Change debug_assert! to assert! in UsbIpResponse::to_bytes() so
  invariant checks fire in release mode, fixing the
  byte_serialize_invalid_usbip_ret_submit #[should_panic] test
