Added support to FileDump for generating binary dumps from MACRO11 listing (.lst) files, since I wasn't having much success with dumpobj or obj2hex.pl; note that this assumes a listing file produced by the macro11 cross-assembler written by Richard Krehbiel in 2001, updated in 2009, and maintained here: https://github.com/shattered/macro11. There are other versions of macro11 floating around, like the one in the simtools project that accompanies simh, and the one built for the Windows-based PDP11GUI app.
