Write down all depdendecies please

Today, after 2 days, I finally come up to understand why your tool unpack the boot.img but leave the 'ramdisk' folder empty.

It is due to my os missing cpio.

But your tool hides all errors and so I made me crazy.

Please, update the read.me will all the dependecies, or check for them before trying to use them
