Generate extra xbox files

[Deterous]

This PR generates the DMI/PFI/SS files that redump.org and abgx360 care about. The functionality is gated behind a --generate-extra-xbox option, so these derivative files are not generated by default.

• {image_name}.dmi is made by trimming the 4-byte scsi header from {image_name}.manufacturer
• {image_name}.pfi is made by trimming the 4-byte scsi header from {image_name}.physical
• {image_name}.ss is made by cleaning the {image_name}.security file with the same method that ss_sector_range uses
  Additionally, the sector ranges are logged when this occurs.

I initially wanted to put this functionality inside redumper split however split only runs for CD dumps, and trying to hack it to run for Xbox dumps results in messy code.
I also wanted to put the DMI/PFI/SS hashes and sector range printing into redumper info however the info step only reads from the main dump (ISO), and hacking it to read from the auxiliary files again results in messy code.
So, the way I've done it is the cleanest way I could come up with.

Alternatively, if you think these files aren't within scope of Redumper, this can be removed/altered.
Instead outputting these derivative files can be within scope of MPF and the like (ss_sector_range)
