GEOENCODE / GEODECODE commands removed.

Rationale:

1. The commands look like internals exposed without a real strong use
case.
2. Whatever there is an use case, the client would implement the
commands client side instead of paying RTT just to use a simple to
reimplement library.
3. They add complexity to an otherwise quite straightforward API.

So for now KILLED ;-)
