/**
* Convert KryoFlux "i4" format dump files to DSK format images.
*
* Usage:
* java KryoFluxDisk [options] [i4_dump_file] [i4_dump_file]...
*
* Output files are created as the same name as the input files
* except with ".dsk" extension.
*
* Options:
* -d create output files in DATA format (default)
* -s create output files in SYSTEM format
*
* Suggested KryoFlux command line to create suitable dump files:
* dtc -fdisk_i4_s0.bin -g0 -e39 -l8 -i4
