nbininv.m: Increase speed (85X) and accuracy of function (bug #34363).
* nbininv.m: Call new function scalar_nbininv to calculate nbininv for scalar.
If there are still uncalculated values then call bin_search_nbininv. Call
bin_search_nbininv directly for vectors. Add more BIST tests.
* nbininv.m (scalar_binoinv): New subfunction to calculate nbininv for scalar x.
Stops when x > 1000.
* nbininv.m (bin_search_nbininv): New subfunction to do binary search for nbininv.
