reader/android: use vanadium-android lib v0.2

This CL updates the gradle script to use io.v:vanadium-android:0.2.
For now, all the vanadium API calls that return a ListenableFuture
are wrapped in sync(), in order to preserve the behaviors.

In the future, the code should be modified to take advantage of the
asynchronous APIs.
