Individual Network Config

[ScottyPoi]

Clients should be able to configure individual networks with unique radius settings.

However, all supported subnetworks are initialized using a global radius value.

This adds a type: NetworkConfig, and updates the type PortalNetworkOpts to accept as supportedNetworks a list of NetworkConfig options instead of simply a list of NetworkId. NetworkConfig includes NetworkId as well as a radius value.

PortalNetwork client code was updated to assign each network its unique radius value.

CLI and test scripts were updated to pass the new NetworkConfig list into client constructors.

export interface NetworkConfig {
  networkId: NetworkId
  radius: bigint
}

export interface PortalNetworkOpts {
  supportedNetworks?: NetworkConfig[]
  ...
}
