Debugged the GDSII driver. Now working with Cadence. 

* Bug: In CRL::GdsDriver::GdsStream two bugs :
    1. The tm fields are int but must be casted into uint16_t in BGNLIB
       and BGNSTR.
    2. The mandatory LIBNAME record was missing.
    3. We also force, for now the dbu to be 1000 and the UU to be 1um.
