Hi, Great work!

according rwkv.cpp forking from llama.cpp
https://github.com/saharNooby/rwkv.cpp ,

Is it possible to make a rwkvcpp port from llama-jni, it could be very cool ,because we can use RWKV 1.5B/3B world model on phone ,and can develop a lot of apps.

If you have any question ,pls contact me QQ:114242123
