Add a few DMX512 dumps.
The files were provided by Fabian Stumpf <sigrok@fabianstumpf.de>
(thanks!) and are released into the public domain:
http://article.gmane.org/gmane.comp.debugging.sigrok.devel/2139
Note: While "--time 1s" was used to create the files, they have
retroactively been shortened to roughly 40ms each.
