Break the captcha + PIN code, as part of a Blacklight challenge: disable a security camera.

Per default, only the case of not incorrect PIN and not incorrect captcha, i.e. what is likely to be the correct PIN+captcha combination, will be printed. For displaying the logs, run with flag -printlog=true

As part of the GopherAcademy Advents Calendar series I wrote a more detailed explanation of the code.

This code is also the base for my talks on the use of TensorFlow with Go from 2018, e.g. at Gotham Go.
