freeotp+ freeotp plus json token reader with QR output

token.py

#! /usr/bin/env python3
# usage: ensure freeotp-backup.json exists in working dir, run this
# if all goes well, it will spit out qr codes. you can enrol these to another authentictor app.
# good luck and try not to break your phone again ;)
#
# known limitations: HOTP is UNTESTED. the counter handling might be wrong. i didn't have any working HOTP to test against
