{fmt} is fast to compile and is comparable to `printf` in terms of per-call
binary size (within a rounding error on this system).
Modular {fmt} is faster to compile than non-modular {fmt}, and both are
comparable to `printf` in terms of per-call binary size (within a rounding error
on this system).

`libc`, `libc++`, and `libfmt` were linked as shared libraries to compare
formatting function overhead only. tinyformat, Boost Format, and stb_sprintf
are header-only libraries.
