`canGoTo` of `BitmapTriplesIterator`

[Chat-Wane]

I noticed a discrepancy between the hdt-version and hdt-cpp on BitmapTriplesIterator's function canGoTo which forbids goTo in the java version, except for ?s ?p ?o:

• In java, it checks if the triple pattern is fully unbounded.

• In cpp, it is just true.

The rest of the code of goTo seems similar, so, should the java version of canGoTo simply return true as well?
