sr: la8 in: Files must be exactly 8388613 bytes. 

All ChronoVu LA8 files (*.kdt extension usually) are exactly 8388613
bytes in size (8MB + 5 bytes). Check this, when trying to autodetect the
file format, to reduce the likelihood of 'chronovu-la8' being
autodetected on all binary files (instead of 'binary').
