Add function Speakeasy.otpauthFromURL

[mircoCampanella]

Hello guys,
you are doing a really good job,
I wanted to propose the introduction of a function that given an otpauth-url would generate
a TOTP | HOTP
example:
let url = Speakeasy.otpauthURL({ ...options });
let otp = Speakeasy.otpauthFromURL(url)

Hi bro, how are you??

Apparently, this repo isn't maintained nowadays. It's sad news. But, there's a repo with no active development, but actually maintained right now: github.com/mlogan/squeakeasy. Maybe better post it there.
