Avoid windows issue with min() max() macros

Including the ``windows.h`` file without defining ``NOMINMAX`` will define the `min()` and `max()` macros which will result in issues compiling any C++ code that uses any variant of `max`, for example `std::numeric_limits<std::streamsize>::max()` and many others.  Although max() isn't used in Fmt anywhere, it is often used in codes that include a format include file so simply upgrading to the current version of lib::fmt will break the windows build which worked prior to the update...
