Import fmt-7.1.3, an alternative formatting library for C and C++

Port by Ashton Fagg (maintainer)

pkg/DESCR:
fmt is an open-source formatting library providing a fast and safe
alternative to C stdio and C++ iostreams.

Features include:

- Simple format API with positional arguments for localization Format

- string syntax similar to Python's format

- Safe printf implementation including POSIX extensions for positional
 arguments

- Fast IEEE 754 floating-point formatter with correct rounding,
  shortness and round-trip guarantees
