Update to 3.3.74
    
    - New upstream release 3.3.74
      - Fix for when a signal name is used as a hierarchy name at the same level of
        scope (affects fsdb)
      - Added --rcvar command line option to insert rc variable changes
        individually without needing to point to a configuration file
      - Change to combine traces down/up routines to handle 2D vector name
        generation
      - Allow FSDB files to contain ".gz" and ".bz2" suffixes as the libnffr loader
        can handle those
      - If a variable is declared in the dumpfile as an integer, then it is
        imported to the waveform display as an integer instead of a hex value; this
        works for dump file formats that show the datatype in the SST window
      - Added code that should prevent the primary marker from disappearing
        unexpectedly as well as dynamic resizing being stuck in the unset marker
        width
