If there are no external programs, such as error checking, etc., DIC outputs
a slightly different set of files. This reduced set needs to be documented in
order for special use cases, such as self-built versions of DIC or removed
helper programs, can be detected to the best of our ability. Below is the list
of files that are generated in that case:

    .bin
    .c2
    .ccd
    .cue
    .img/.imgtmp
    .scm/.scmtmp
    .sub/.subtmp
    _cmd.txt (formerly)
    _img.cue

This list needs to be translated into the minimum viable set of information
such that things like error checking can be passed back as a flag, or some
similar method.

Here are some notes about the various output files and what they represent:
- bin           - Final split output disc image (CD/GD only)
- c2            - Represents each byte per sector as one bit; 0 means no error, 1 means error
- c2Error       - Human-readable version of `c2`; only errors are printed
- ccd           - CloneCD control file referencing the `img` file
- cmd           - Represents the commandline that was run
- cue           - CDRWIN cuesheet referencing the `bin` file(s)
- dat           - Logiqx datfile referencing the `bin` file(s)
- disc          - Disc metadata and information
- drive         - Drive metadata and information
- img           - CloneCD output disc image (CD/GD only)
- img.cue       - CDRWIN cuesheet referencing the `img` file
- img_EdcEcc    - ECC check output as run on the `img` file
- iso           - Final output disc image (DVD/BD only)
- mainError     - Read, drive, or system errors
- mainInfo      - ISOBuster-formatted sector information
- scm           - Scrambled disc image
- sub           - Binary subchannel data as read from the disc
- subError      - Subchannel read errors
- subInfo       - Subchannel informational messages
- subIntention  - Subchannel intentional error information
- subReadable   - Human-readable version of `sub`
- toc           - Binary representation of the table of contents
- volDesc       - Volume descriptor information
