While it's definitely something that should be explored later on when libeuropa is a larger library, and has C ABI wrappers to better foster bindings between other languages like Rust and such, for now, libeuropa is both pretty entertwined with both the C++ standard library and STL, and still in heavy development, so I think doing this isn't a good move.
This completely redoes the garbage flags stuff I did before. OOPS. This seems a lot closer to the format, and also exports everything Starfighter has properly.
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`.
