Reconsider forking frida-mono-api

[Techbrunch]

I would be nice if frida-mono-api had it's own repo since the original repo does not appear to be maintained anymore.

I agree that the current situation isn't ideal. Forking would be better indeed. I'll look into it soon. Forking would also improve the UX of Fridax since it wouldn't require including the frida-mono-api by relative path anymore, allowing us to distribute Fridax as an NPM package.
