1.9.0 - Goodbye cpp11

This will be the last release where the minimum required C++ standard is cpp11. With the next major release (1.10.0) in ~late 2022/early 2023 we will increase the minimum C++ standard to cpp17 (Issue).
This release (1.9.0) will still receive bug fixes, at least until the end of 2023, but all new features require from now on a cpp17 compatible compiler.

Thanks to everyone who helped making this next release of cpr possible 🎉!
Especially I would like to thank @simon-berger, @saendigPhilip @leviliangtw .

In case everything goes like planed we will even offer a .deb package and a NuGet package soon.
So stay tuned!
