Unable to open L01 storing sparse data stream like $UsnJnrl:$J

[sleepynox]

$UsnJnrl:$J is stored with many extents including sparse areas.
Normally the first extent starts with a sparse area.
The current libewf library cannot open those L01.

The following is the sample.

libewf_lef_file_entry_read_data: type:  be with value:
00000000: 32 20 53 20 38 34 31 37  30 30 30 30 30 20 31 20   2 S 8417 00000 1

and libewf_lef_file_entry_read_binary_extents currently expects 1 or 3 values
