*u8: add support for checking if an archive was packed with wii.cs to allow fixing it

Browse Source 
use case-insensitivity.  seems all the nintendo tools are running on windows and in the system menu html, paths are case-insensitive.  it doesnt seem like there is anywhere where they would need to be the other way

* lz77: support for unpacking archives larger than 0xffffff bytes

* nusdownloader: dont try to write files to cache if there is not one set
