0.12.3: Compilation issues on various platforms

New features:

There was a de-seventeen-ification atempt, which was scrapped, except for:

• simple_span, which replaced the std::array used with CTAD.
• converter<char const*> and converter<char*> are now as invalid as the std::string_view version
• action_base::names_ vector is now pre-allocated for the incoming name list

Bugfixes:

• Apple Clang gets the same compilation flags as Clang, or to be exact, it does not get GCC-specific ones.
• Apple Clang libc++ does not sneak <errno.h>, it is now added to allow compilation
• MSVC 16.4.4 adds __cpp_impl_three_way_comparison, but cannot compile automatic <=> without verbose inclusion of <compare> header (while later version don't); single instance of this operator was removed for now.
• MSVC 16.4.4 does not sneak <algorithm>, it is now added, so std::max can compile.

Conan:

This is first version available on conan-center repo, as mbits-args/0.12.3.

0.12.1: Add support for a shared library

New CMake variable, LIBARGS_SHARED, will build libargs.so and args.dll instead of libargs.a and args.lib, respectively (except, of course, args.dll will also produce args.lib).

0.12.0: Support for @answer-files

New feature:

• support for @answer-files

Fix:

• change getter from parser::provide_help() to provides_help()

0.11.0: Enums and UTF-8

Small update of library functionality.

New features:

• support for enums as destination for an argument value
• support for equal sign, as in --argument=value

Fixes:

• Various small fixes for Windows / MSVC

0.10.0: First actual realease

Small library for program argument parser, inspired by Python's argparse, for C++17/20.

• automatic -h / --help support
• positional arguments
• arguments with and without value
• custom arguments with a callback
