Added support for selecting Magicka game versions from CLI and improved automatic unpacker version detection support.
Unpacker ops can now have the expected input Magicka version specified with the -I <version> command.
Packer ops can now have the expected output Magicka version specified with the -O <version> command.
Valid version strings for -O and -I commands:
"new": Modern Magicka (1.10+)
"old": Legacy / Old Magicka (1.4, 1.5, etc...)
"auto": Automatically determine the version of the file for input files (unpack ops), always write for modern magicka for output files (pack ops).
