Implement network score module from cord.js in Golang

[NiranjanAP]

Refer https://github.com/dhiway/cord.js/tree/develop/packages/network-score, this is the network scoring module. This needs to be built in Golang to help some users who have Golang as their primary development language.

Note: You'll have to identify and build some of the other modules that are dependencies for this to work, hence a high level of understanding of the SDK will help.
To get a good overview of the the SDK, Go through the demo script https://github.com/dhiway/cord.js/blob/develop/demo/src/func-test.ts and documentation for the same at https://docs.cord.network/cordjs/integratecord/

depends on #2 Once the basic core modules are complete, this can be done as a separate task.
