Added support for `options` for `getQuote` method

With this release, getQuote method will start accepting options.

const Quote = require('inspirational-quotes');
console.log(Quote.getQuote({ author: false }); // return quote without author

By default, author info will be returned.

Default options: { author: true }

NOTE: This version supports the legacy getRandomQuote method that might be deprecated in further versions. Recommended to use getQuote method with options as { author: false }
