Archives: Change the folder layout of some archives.

This is to better represent the hardware layout, they are still aren't quite accurate, for example the extdata in the nand should be under an extra <ID0> folder, where <ID0> is a hash over some data inside a movable.sed file, since we don't use that yet i don't see the point of placing it there.
This will help a bit when implementing the other archives like NAND-RO and NAND-RW
