blocks: remove bin_statistics_f block due to swig dependence
The bin_statistics_f block relies on the SWIG director functionality and
therefore will need to be rewritten in the transition to pybind11.
Additionally it does not appear documented in any way and there are no
example flowgraphs, so it is questionable whether anyone is using it at
this point
