Fix include to avoid MSVC compilation error

[thbeu]

Avoid MSVC compilation error C2039: "min": is not a member of "std" of Visual Studio 2017.

Could you please wrap this in #ifdef _MSC_VER <whatever 2017 is>?

That way I know I can remove it when I drop support for MSVC 2017.

Thanks!

This is not necessary, since std::min and std::max are defined in header <algorithm>, see https://en.cppreference.com/w/cpp/algorithm/min. Thus, this is a proper C++ fix and independent of the actual compiler. It just happend, that I observed it with VS 2017.
