Allow subdomain resolution

[mdatsev]

Here's the code to test it:

const { Web3Resolver } = require("./lib/index.js");
const web3resolver = new Web3Resolver();

(async () => {
  console.log("domain: ", await web3resolver.resolve("test8888.888"))
  console.log("subdomain: ", await web3resolver.resolve("888.test8888.888"))
})();

You should add SUB_DOMAINED_DOMAIN to the ResolvedResourceType enum and add the case to handle subdomains in the getResolvedResourceType() function in name-tools.ts
