Implement authenticated request + add getUserHistory

[rhld16]

Here's a early implementation of authenticated requests for YouTube Music. This could eventually lead to this library being able add or remove songs from playlists but for now, the only authenticated method I added, for demonstration, is getUserHistory()

Here's an example of how authenticated requests would go:

const YoutubeMusicApi = require('../index.js')

const api = new YoutubeMusicApi()
api.initalize('INSERT_COOKIE_HERE')
.then(info => {
    api.getUserHistory().then(result => {
           console.log(result)
        })
})
