Update histogrammar to v1.1.1
In numpy 2.3, converting np.number to a dtype no longer allowed.
See: numpy/numpy#28254
"When constructing a dtype from a class with a dtype attribute, that attribute must be a dtype-instance rather than a thing that can be parsed as a dtype instance."
hist.datatype now returns float instead of np.number as datatype.
