1.10.0 - Welcome cpp17

With this release we are increasing the minimum required C++ standard from cpp11 to cpp17.
BUT since we know not all of your projects are able to support a C++ standard <= cpp17, we are still supporting cpr 1.9.x until 01.01.2025. From now on the 1.9.x release will only receive bug fixes.
