fix(vulnerability): Prototype Pollution Vulnerability

[zero734kr]

Screenshot proving that injection has occurred:

Note that port 43 in error and port in prototype are same

This pull request is to prevent tentatives of prototype pollution

How to reproduce:

whois.lookup("__proto__", (err, data) => console.log(data))
const obj = {}
console.log(obj.__proto__)
// [Object: null prototype] { port: 43, query: '$addr\r\n' }

I'm trying to fix indent error thrown by coffeescript, but I never experienced CoffeeScript and don't know what to do to solve. Can you solve this, please?

@zero734kr Thanks for the PR. Sorry to take so long to get to this. I have fixed the spacing issue in b98c076.
