Rewritten the main loop of the code as it was previously used only with test data; it is very close to final now.
Imaging to multiple files and formats at the same time now works.
Any step of dumping, analysing and imaging a track only happens when it is needed; already available data gets reused.
Added support for exporters without file association. This makes it possible to check dumping integrity against an arbitrary number of built-in formats, even if the file output is not needed - even just using the tool for a disk integrity check is now possible.
