pycrate repo update

Dear osmocom developpers, This is just to let you know that the Python library pycrate has a new home : https://github.com/pycrate-org/pycrate. The packages on Pypi are now feeded from there. This library can be used in many cases dealing with mobile signalling. I wanted to let you know, as even if I am not aware of any osmocom projects depending on it, some of you may use the library from time to time, or could have local applications depending on it. Best Regards Benoit
