Missing documentation for chipTAN+QR

[pc-coholic]

The Sparkassen have discovered, that waiting to transmit the chipTAN-data via flickercode takes bloody ages at times and came up with something new and revolutionary: a QR-code!

As far as I can tell, the same data that goes into the flickercode is just put inside a QR-code for scanning convenience. Seems like there is going a little bit of encoding going into the QR-code: https://gist.github.com/pc-coholic/6275c47ce75220470c25fe5cd324f904

As of now, it's only used at select Sparkassen, with a global rollout planned for 2019.

I'll have a Reiner-device that I can provide for testing.

I think current master already solves that thanks to Henryk: #54

Feel free to test and report back :)

Yes, seems like it... I didn't see that as I just checked the docs... Sorry for the noise. Will test and report back.
