Integrate browser geolocation API (#9)

* Add GPS service and nautical base city data

- Implement `GpsService` with methods for position updates and enabling/disabling GPS.
- Introduce test data for nautical base cities with key attributes like population, coordinates, and images.
- Update dependencies in `bun.lock` with required packages such as `geojson`.

* give map a custom style

* shift towards rust exclusivity

* `build.rs` streamlines map build. Added an axum server with the map assets embedded.

* update readmes

* base-map api retrieves geolocation from the navigator of the browser

* make map standalone wry that pulls assets from the server to simulate behavior in bevy

* wip wasm

* wasm build fixed

* fix path ref to assets
