support Redump extended bin/cue format for Dreamcast discs (#7422)
* initial check-in of Redump bin/cue support for Dreamcast GDI * correctly identifies multi-cue format and sets GDROM flags * creates a working Crazy Taxi chd from a Redump bin/cue * disabled debugging code and started tidying up * simple tool to compare chdman bin/cue and bin/gdi conversions, should be identical * final tidy up, the testing is going well * testing failed for Aero Dancing i (Japan), didnt zero last track * added some comments about .gdi compatibility * addressing review feedback on pull request #7422 * match TOSEC layout for Pattern I discs (3 tracks) * initial support for Pattern III discs * Pattern III discs now work and match TOSEC layout * reading datasize from wrong track, same result though * identify the GDI pattern, makes the code clearer * support for Pattern II and consecutive AUDIO tracks * use C99 type not POSIX type to build on Windows * support Redump tracks split across two .bin files
