v1.0.3

• Routing:
  • GraphRouteFinder:
    • Added profile field to select transport mode for routing.
    • Updated graph loading and existence checks to use (graphId, profile) keys.
  • AStarRouter, DijkstraRouter, ContractionHierarchyRouter:
    • Added optional profile parameter to constructors.
• OSM Conversion:
  • OsmConverter:
    • Updated convert method to store graphs scoped by profile.
• Storage:
  • GeoStorage interface:
    • Added profile parameter to all methods to key graphs by (id, profile).
  • CompiledGraphStorage interface:
    • Added profile parameter to saveCompiled and loadCompiled.
  • LocalFileStorage:
    • Updated file naming to include profile (e.g. <id>_<profile>.graph).
    • Updated all storage methods to accept and use profile.
    • Added checksum verification and metadata recording per profile.
• Example:
  • geo_route_finder_example.dart:
    • Simplified graph id usage to exclude profile suffix.
    • Updated router instantiation to pass profile explicitly.
• Model:
  • GraphMeta:
    • Added profileName field to record transport mode.
• Tests:
  • serialization_test.dart:
    • Updated tests to verify profile-specific storage keys and independent graphs per profile.
  • support.dart:
    • Updated MemoryStorage to key graphs by (id, profile).
• Misc:
  • Added profile parameter propagation throughout routing and storage layers to support multiple transport modes stored under the same graph id.
