vir-simd 0.3.200 (beta 1)

ChangeLog:

	* .github/workflows/CI.yml: Test installation. On MSVC builds
	compile the check target.
	* CMakeLists.txt: Require cmake 3.5. Set
	CMAKE_CXX_VISIBILITY_PRESET and CMAKE_VISIBILITY_INLINES_HIDDEN.
	Build test.cpp only for the check target, not all.
	* Makefile: Interpret patchlevel as release, development, alpha,
	or beta and print on 'debug' and 'install'.
	* vir/simd_version.h: Bump patchlevel to 200.
	* vir/test.cpp: Remove tests for exact version number.
