0.70.0-1 - split -bin and -common packages
    
    ...the former becoming the only arch-specific
    - also move python-specific (entry points, main files) back from -cli
      package
    - also rename python-clufter to python2-clufter (former is a legacy
      alias)
    - also leverage the above modularization to package python3-clufter in
      parallel
    - bump upstream package (version rolling the above changes out)
