Vcpkg port of the library

[TerensTare]

Hey there! I was looking for a test library to use for a personal project and I must say the macro-free API and (relatively) modern C++ features usage made me choose this library for testing. I use vcpkg for managing my dependencies, so I did a search to see if the library is available on vcpkg, but there was no issue/PR on both repos mentioning it, so I assume there is no support. I am pretty sure package managers are widely used for C/C++ projects nowadays, so I think many developers will profit from the library being available on vcpkg or other PM-s.

For anyone waiting for this, there's the bext-ut port on vcpkg.
