Map rendering Works but I don't want to use Tileson so I'm gonna change that

Mainly bc Tileson requires std::filesystem, which my clang is too old for apparently, and while I can use gcc instead I just want to not, I suppose. Also Tileson's API is very weird RE const correctness? Idk. And also being able to parse the tmx files rather than exporting to json would be preferable.
