getOSPFStatistics method

Map<String, dynamic> getOSPFStatistics(OSPFRoutingTable<T> routingTable, Map<T, List<LinkStateAdvertisement<T>>> lsdb)

Gets OSPF statistics for monitoring and analysis

routingTable - Routing table to analyze lsdb - Link-state database to analyze

Returns map with various statistics
