libpixel (suprisingly) still compiles, but depends on libraries in a very annoying manner that makes EuropaTools hard to compile. Also, I don't like stb_image_write.
Replace it with some hand-done structs and the simpler/faster/better `lodepng`.

This really needs to be cleaned up before I'm willing to call it "good" but ultimately the API changes here needed to be done anyhow
