    Representation (CBOR) data format for the RIOT-OS.                                                                                                                                                     
                                                                                                                                                                                                           
    This implementation mostly stand-alone, and it should be pretty easy to

    - CBOR_NO_CTIME: All ctime related features removed
    - CBOR_NO_FLOAT: All floating-point related features removed
    - CBOR_NO_STREAM_DECODE: Generic decoding feature removed
      (cbor_stream_decode normally prints out a CBOR data stream to stdout)
