To decompress some output file(s), simply pass -z <idx> where idx is the index
of the file to decompress, starting from 0. For example
upgtool -e NW_WM_FW.UPG -o tmp/ -m nw-wm1a -z 6 -z 7
to decompress files 6 and 7. To compress file, use the same options:
upgtool -c NW_WM_FW.UPG -m nw-wm1a -z 2 script.sh md5sum.txt system.img

In order to avoid the crypto++ mess, the code uses the Windows Cryptography API,
which is standard. There is also some makefile magic to cross-compile:
make PREFIX=i686-w64-mingw32- EXE_EXT=.exe
I selected the option so that it should statically link supports libraries used
by gcc (slsj and libwinpthread).

The new code supports reading and writing UPG files. I kept the old keysig
search code but it only supports the old format (the new format has too long
keys anyway). Since we now have to support two types of encryption(DES and AES),
I reorganized the crypto routines and clean-up some code.

Split WM1A/WM1Z because they don't have the same KAS. On newer devices, the KAS
is actually 64 bytes, not 60. The strange thing is that "get_dnk_nvp kas" returns
60 bytes whereas "get_dnk_prop kas" returns 64, not sure why.

Strangely it has the SAME encryption key as the E450. Either they didn't bother
changing it or more likely they have exactly the same internals and a slightly
different case.

* added KAS for nwz-x1000 (extracted from an NWZ-X1060 via "get_dnk_nvp kas")
* hint that -o is needed when extracting

We don't know the encryption method, the KAS is completely different but it
might be useful to record it anyway for future purposes. MID extracted from
device, Japanese NW-A35.

We already use Crypto++ for DES anyway, and using OpenSSL is not great because
of its incompatible licence.
