Add "z" format specifier to coerce negative 0 to zero. See https://github.com/python/cpython/issues/90153 (originally https://bugs.python.org/issue45995) for discussion. This covers `str.format()` and f-strings. Old-style string interpolation is not supported. Co-authored-by: Mark Dickinson <dickinsm@gmail.com>
