Build a bin statistics block. See qa_bin_statistics.py and gr-uhd/examples/python/usrp_spectrum_sense.py for examples of its use, specifically how to use the callback function.

Parameters

vlen	vector length
msgq	message queue
tune	a feval_dd callback function
tune_delay	number of samples for the tune delay
dwell_delay	number of samples for the dwell delay
