fmtlib uses consteval format string processing, which makes it more efficient than std::snprintf(). snprintf()s in libuv, mpack, processstarter, and wpigui were left alone. processstarter uses stdlib only, and wpigui only depends on imgui. fmt::format_to_n() is analogous to std::format_to_n() (https://en.cppreference.com/w/cpp/utility/format/format_to_n) wpi::format_to_n_c_str() is a wrapper which adds the trailing NUL.
