Pull Request description

now we can use hdl_dump as source for the linux device-mapper : hdl_dump toc /dev/loop0 --dm | sudo dmsetup create --concise ( that equivalent to kpartx -a disk.img with our sony APA disk ).

Now , size on ISO is accurate, you can directly checksum the mapped device and find the right number according to redump.org . No additional project like apascan to maintain, and much.
