Add support for extracted WiiU games

[Masamune3210]

I know that rp just got support for showing info on WUP packages, but would it be possible to extend that to the resulting folder after extraction of the package? All the files are still there, under the meta folder, complete with meta.xml and assorted tga files

As you can see, they are decrypted, so no fancy crypto magic needed

Should be doable; instead of using the H3 reader, we can just read the directory as-is. Will test it out tonight.

Please test the latest build once it's available:

Sidenote: title.tik and title.tmd are always available in NUS packages, but usually aren't available in extracted packages. (The TMD might be available for titles copied directly from eMMC or USB storage, but the ticket is stored in SLC.) Those files will be skipped if they're missing (assuming they should be in the code/ directory), but if they're found, they'll be displayed.

Will try to test tomorrow unless someone gets to it first, just got my computer back together after having to change out the cooling and I'm a bit burnt out
