ofUtils warnings - snprintf, requires a string literal

we can add fmt lib to the core to deal with format

/Volumes/tool/ofw/libs/openFrameworks/utils/ofUtils.h:600:45: warning: format string is not a string literal (potentially insecure) [-Wformat-security]
        size_t n = std::snprintf(buf, sizeof(buf), format, std::forward<Args>(args)...);

/Volumes/tool/ofw/libs/openFrameworks/utils/ofUtils.h:600:45: note: treat the string as an argument to avoid this

Start by reviewing libs/openFrameworks/utils/ofUtils.h around lines 600 and 612, where the reported std::snprintf warnings occur, and inspect the surrounding formatting entry points. Build the affected target to reproduce the warnings and evaluate the proposed fmt approach; done means the warnings are resolved without breaking formatting behavior.
