offset fetcher + modularization + imgui tweaks

basically the offsets updated approximately 8 hours ago so thats when i realised im going to have to have a built in offset updater. basically whenever you start the exe it pulls the latest offsets from these two links https://raw.githubusercontent.com/a2x/cs2-dumper/refs/heads/main/output/offsets.rs and https://raw.githubusercontent.com/a2x/cs2-dumper/refs/heads/main/output/client_dll.rs then compares them to the cached ones and updates them if they are different.

i also modularised the code as all code was just in one fat 1800+ line main.cpp now we have like lots of different files. I also added money ESP and c4 esp (my personal favourite as it shows time to detonate). I am about to upload this onto github so then the world can see this as I havent even uploaded anything yet.
