feat(collectors): add ArcGIS landing points and cable-landing relation collectors

- Add ArcGISLandingPointCollector for FeatureServer/1 (landing points)
- Add ArcGISCableLandingRelationCollector for FeatureServer/3 (cable-landing relations)
- Register new collectors in __init__.py
- Fix earth cables.js with cable_id grouping for highlight
