Short Description: Generic C64 prg unpacker

Original source and idea: testrun.c, taken from Exomizer 2.0b7 by Magnus Lind.
Converted to a generic prg unpacker by iAN CooG. Being a derived project,
Exomizer' sources used for UNP64 are included and modified where needed.

The idea is simple: to simulate the C64 memory/processor, run the program until
it reaches the unpack routine, usually relocated to an address lower than $0800,
then to continue execution until the Program Counter returns to a normal address
usually higher than $0800. At this point, save all the memory.
I normally do this process in emulators by setting breakpoints but an automatic
program that does it for me is handy.
PUCrunch and Exomizer 2.0Beta7 already have their own decrunch commands.
This program should cover those 2 and almost all the remaining ones.
