DATAMATRIX: new algorithm for (near-)minimal encoding, props Alex Geller

Browse Source 
Add FAST_MODE input_mode flag and --fast CLI/Tcl option that selects older
  faster ISO algorithm (may be used by other symbologies in the future)
  and "Fast Encoding" checkbox to Data Matrix GUI
GUI: adds Zint version numbers to DATAMATRIX sizes.
