[Bug] GCC 13 compilation error

[oceanusxiv]

What happened?

It appears that GCC 13 started enforcing stricter adherence to the C++ standard and we now must include cstdint in order to have access to the builtin types. VC suffers from this issue in both its own codebase

Thanks for reporting. I've been slowly updating these instances as I've come across them, but since it wasn't causing compilation errors, I hadn't found them all yet. Should be a quick fix.
