Gpyes integration (#11)

* Introduce core modules: device management, bus communication, and discovery protocol. Adds system device interface, virtual hardware bus, and device discovery logic. Includes tests for all components.

* improve map
- Fix typos in variable and function names (`vessle` to `vessel`).
- Add `update_vessel_data_with_gps` function to enable GPS integration for vessel data updates.
- Integrate real GPS data into vessel systems and UI components (speed, heading, etc.).
- Initialize speed gauge display at 0 kts.
- Include `useEffect` in `MapNext` to log and potentially handle `vesselPosition` changes.

**Add compass heading update system using GPS heading data.**

- Remove `UserLocationMarker` component and related code from `MapNext.tsx`
- Simplify logic for layer selection and navigation within `App.tsx`
- Replace map style 'Bathymetry' with 'OSM' in layer options

improve map
