Windows support

[jacobperron]

Changes to supporting building on Windows (3aa08a8).

• Add missing visibility macros, including CMake target definition
• Fix build error passing std::filesystem::path instead of std::string
• Fix linker error building against yaml-cpp
• Quiet warnings caused by including "yaml-cpp/yaml.h"
• Fix build warning in test_domain_bridge.cpp

Also trying to add Windows CI to the GitHub workflow (db17a54)

Closes #57
