[fmt] chrono.h, color.h: Suppress some MSVC warnings.

Browse Source 
These warnings (now handled as errors) appeared in the AppVeyor build
with MSVC 2015:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\algorithm(1669): error C2220: warning treated as error - no 'object' file generated [build\src\amiibo-data\amiiboc.vcxproj]
C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include\algorithm(1669): warning C4996: 'std::reverse_copy::_Unchecked_iterators::_Deprecate': Call to 'std::reverse_copy' with parameters that may be unsafe - this call relies on the caller to check that the passed values are correct. To disable this warning, use -D_SCL_SECURE_NO_WARNINGS. See documentation on how to use Visual C++ 'Checked Iterators' [build\src\amiibo-data\amiiboc.vcxproj]
