* Made the fast binary to decimal floating-point formatter the default and
sligthly improved its performance. {fmt} is now 15x faster than libc++'s
``std::ostringstream``, 11x faster than ``printf`` and 10% faster than

* {fmt} no longer converts ``float`` arguments to ``double``. In particular this
improves the default (shortest) representation of ``float``s and makes
``fmt::format`` consistent with ``std::format`` specs

* The overload of ``print`` that takes ``text_style`` is now atomic, i.e. the
output from different threads doesn't interleave
