Review Comment:
@tabish121 we could add other libraries that are using ffm later. Mayank is
doing some experimentation with ioUring... we could add that into this module
if it gets any useful.
Not that I foresee many other libraries in the future.. but what if we ever
add more?
I didn't want to use the word native as native itself is a reserved name in
java, and to not confuse with the current JNI implementation.
