NPM versioning issues: Cannot find module './config/EthereumDIDRegistry.json'

[0xKai27]

Describe the bug
I was trying to follow along with the quickstart at https://www.npmjs.com/package/ethr-did-resolver but was unable to compile my project as there is a missing module in the ethr-did-resolver library. I've checked the installed node_module against the code base on github and I can see that ./config/EthereumDIDRegistry.json exists on github but doesn't get installed with npm.

To Reproduce
Steps to reproduce the behavior:
Follow the "Resolving a DID Document" section at https://www.npmjs.com/package/ethr-did-resolver

Expected behavior
Able to compile with no issues
