=head2 check_bootsector($fields)
 
Takes a hash reference with decoded fields of a bootsector; returns
TRUE if minimal sanity checks hold; die()s otherwise.
 
=head2 interpret_directory($dir, $is_fat32, [$keep_del, [$keep_dots, [$keep_labels]]])
 
  ($res, $files) = interpret_directory($dir, $is_FAT32);
  $files = interpret_directory($dir, $is_FAT32);
 
Takes catenation of directory cluster(s) as a string, extracts
information about the files in the directory.  Each element of array
referenced by $files is a hash reference with keys
