Proguard rules for Android release builds

[Ethan1983]

Hello,

As the native code is referring to Java classes by reflection, could the library com.uber:h3-android also expose pro guard rules for R8 release android app builds?

        jclass local_latLngClass =
            (**env).FindClass(env, "com/uber/h3core/util/LatLng");

        jclass local_h3eClass =
            (**env).FindClass(env, "com/uber/h3core/exceptions/H3Exception");
