Lurs' squashed commits

* first tphd wip

* fix CMakeLists.txt after rebase

* fix mipmapping (I hope) thanks to decaf-emu. Skipped a few textures in favor of GC assets and added new HD asset file formats

* added third hook into dusk for second JKRMemArchive constructor (e.g. for sign textures). skip texture load for textures with imageoffset = 0 to get STG.arc loaded instead. And small refactorings/rebasings. added a few parameters in logging
