Added shell script that demoes the usage of the GHDL simulator with the

dp_repack_data core and its dependencies.

+# Author:
+# . Daniel van der Schuur
+# Purpose:
+# . Test our VHDL code the GHDL compiler/simulator.
+# Usage: 
+# . Execute: ./ghdl_test.sh
+# Description:
+# . Requires a working install of the GHDL simulator.
+#   . This script was tested with:
+#     $ ghdl --version
+#       GHDL 0.36-dev (tarball) [Dunoon edition]
+#       Compiled with GNAT Version: Community 2018 (20180524-73)
+#       mcode code generator
+# . The waveform can be written by uncommenting the corresponding line below
+#   (wave.vcd)
+# . The written waveform can be viewed using e.g. GTK Wave Viewer.
+# . The simulation runs fine, but is (2min vs 1min) slower than ModelSim 6.6c,
+#   probably due to a memory leak (it uses about 10GB of RAM).
+#   . Apart from the mem leak, another back end (rather than the mcode backend)
+#     could be used (GCC or LLVM) to increase sim speed.
