[scnlib] Add new port

[SuperWig]

The support for range-v3 doesn't work with the fork vcpkg has so I disabled it.

Edit: Now realising that vcpkg doesn't use the Microsoft fork as indicated by the control file.

I'm unfamiliar with UWP but I assume the library doesn't support it?
Should the description include (pre-release) in it?

Thanks for doing this; I don't know vcpkg, so it's good that someone knowledgeable would do this for me.

Couple of points:

• Version should be 0.1.2, and the head reference should be updated
• Homepage should be https://scnlib.dev
• To disable the ranges target, set -DSCN_RANGES=OFF instead of -DCMAKE_DISABLE_FIND_PACKAGE

I don't know about the UWP error; that's just a warning on Appveyor on Windows. Maybe do what abseil does:

vcpkg/ports/abseil/portfile.cmake

Lines 3 to 5 in 1004b2e

	if(VCPKG_CMAKE_SYSTEM_NAME STREQUAL "WindowsStore")
	message(FATAL_ERROR "Abseil currently only supports being built for desktop")
	endif()

WindowsStore is UWP, right?

Thanks, updated!
I didn't realise that the logs were accessible. Apparently the UWP build fails because of this

visitor.cpp(517): error C4146: unary minus operator applied to unsigned type, result still unsigned

Curious as to why this is treated as an error for UWP but not x86?

And thank you for the library :)
