work in progress ...
inspired by the ccc talk:
"BlinkenCity: Radio-Controlling Street Lamps and Power Plants" (https://media.ccc.de/v/38c3-blinkencity-radio-controlling-street-lamps-and-power-plants)
gnu radio example of decoding DCF39.
Currently only outputs the hex-part in a "valid_bytes.bin":
68 0a 0a 68 37 00 00 00 30 25 0e c4 01 19 78 16
Information about the protocol based on germany:

TODO:
Actually decode the messages themself, and validate by checksum.
