Multiple performance updates, to Bin, SparselyBin and Categorize histograms.

SparselyBin, Categorize: optimized filling with 1-d and 2-d numpy arrays
Bin, SparselyBin, Categorize: (fast) numpy arrays for bin-centers and bin-labels.
Count: new, fast filling option when float weight is known.
util.py: faster get_datatype() and get_ndim() functions.
