failed to establish tcp connection on session connect

This is somewhat blocked by #50, since failing to load via the NativeSession's static block will prevent the runtime from getting initialized properly, which blocks everything else.

However, if you follow the suggested approach from #54 and copy the .so into your android project's JNI libs folder and load the library ahead of time, you can almost make it work. You still need to move the call to Runtime.init out of the try block where Runtime.load throws an exception.

Anyway, if you get all that accomplished, you can successfully call into Rust, which presents you with this lovely stack trace:

Not super informative, but hacking up ngrok-java-native to stuff more context into that error tells us: failed to establish tcp connection to connect.ngrok-agent.com: failed to lookup address information: No address associated with hostname

Soooo DNS isn't working right? That's about as far as I've gotten. Possibly some nuance of android app networking that I'm not aware of, or maybe a bad system resolver being used by the rust lib?
