Sky3DS DiskWriter Python Clone 3DS

Hey there,

I'm currently working on a Python version of DiskWriter to be able to use it on Linux and OSX machines.

Not sure if anyone attempted this before, I wasn't able to find much information on how DiskWriter stores data to the sd-card, so I had to figure out most by just looking at hexdumps of my sd-card.

The tool is actually already working. Under OSX it can't detect the disksize (yet), but I am working on that. If you know how to do things in python you can hardcode the size and this tool will work!

Things I still want to improve: 3dz unique-id import (instead of using the data from template.txt), unique-id re-import on savegame import. Both should be relatively easy, I just didn't really need those features yet, so I didn't do that work.
