MAINT: Simplify IntegerFormatter

This essentially reverts 83accefd143a0e3ee8b3160d0927b3ff616743de, which presumably worked around a bug in an ancient version of python

Similarly, the try/excepts here were to handle `IntegerFormatter` being called on the wrong type of array, which no longer happens
