Observers are not implemented at all in Cuberite (what are they, anyway? :)

@madmaxoft IIRC They were first added to PE as a proper BUD block and were later added to the Java version.

In Java Edition, an observer will detect changes in its target's block ID or data value, or the breaking or
placing of a block (i.e. changes in its basic block state, but not its extended/actual block state). This means
that changes like the age of crops will be detected, since they are part of the basic block state that is
converted to metadata when the world is saved; however, changes such as the shape of a fence will not
be detected, since those are part of the extended block state, which is not saved when the world is saved.
