sounds like word salad but let me say: - std::map<> created a static ctor for EVERY SINGLE ZONEINFO - fuck that, instead lets just use a raw array and construct things statically - works the same except with less baggage carried around (+ less heap allocations!!!) this should help reduce codesize due to the aforementioned global ctor/dtor Signed-off-by: lizzie <lizzie@eden-emu.dev> Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3919 Reviewed-by: crueter <crueter@eden-emu.dev>
