Data Fields
uint8_t	sequence
	Track number (1..99 typical for CD audio/data). 0 may indicate placeholder/non-standard.
uint8_t	type
	Track type (value from TrackType).
int64_t	start
	Inclusive starting LBA of the track.
int64_t	end
	Inclusive ending LBA of the track.
int64_t	pregap
	Pre-gap length in sectors preceding track start (0 if none).
uint8_t	session
	Session number (1-based). 1 for single-session discs.
uint8_t	isrc [13]
	ISRC raw 13-byte code (no null terminator). All zeros if not present.
uint8_t	flags
	Control / attribute bitfield (see file documentation for suggested bit mapping).
