hyperspace cores are not announced: hyperspace/server.js is not calling db.putNetworkConfiguration() anywhere

[KrishnaPG]

In the server.js the networker.configure() method (required for announce) is dependent on db.listNetworkConfigurations() (see below):

https://github.com/hypercore-protocol/hyperspace/blob/26d6d36f3d3f9d6ca1269994af5a2ddf9096c583/server.js#L120-L125

However, no where in the server.js file the db.putNetworkConfiguration() is called, which means the db.listNetworkConfigurations() always returns empty, thus the cores are not announced.
