The current implementation has no plugin support. I expect that we'll be able to share most or all of the Linux code for the plugin infrastructure (although if Windows provides a built-in JSON parser, we'll presumably want to use that instead of jsoncpp).

If we can't use the same code, then the Windows version should not follow the macOS/Linux example, since I plan to rewrite both per #102. Instead it should be written directly to the end-state of the macOS/Linux refactoring (which would mean something very much like the Flutter Android implementation).
