// Some people have broken (older) dumps where a two second pregap was implicit but not specified in the cuesheet.
// The problem is we can't tell between a missing implicit two second pregap and a zero second pregap. Most of these
// seem to be a single bin file for all tracks. So if this is the case, we add the two seconds in if it's not
// specified.
// specified. If this is an audio CD (likely when track 1 is not data), we don't add these pregaps, and rely on the
// cuesheet. If we did add them, it causes issues in some games (e.g. Dancing Stage featuring DREAMS COME TRUE).
