I made an implementation of Steams TOTP for python based on the mentioned [otp.rs](https://gitlab.gnome.org/World/Authenticator/-/blob/master/src/models/otp.rs). https://gist.github.com/einfachIrgendwer0815/883a7d1f4e328b839fa3ddacca1b10d2 It's a subclass of `pyotp.TOTP` and overloads `generate_otp()`.

@JamiKettunen Are you working on this? Otherwise I would like to do that.
