naming). If itemsize is given it must be >= size computed from fields
The .fields attribute must return a convertible dictionary if present. Result inherits from NPY_VOID.

This function takes a Python object representing a type and converts it to a the correct PyArray_Descr * structure to describe the type.
Many objects can be used to represent a data-type which in NumPy is quite a flexible concept.
This is the central code that converts Python objects to Type-descriptor objects that are used throughout numpy.
Returns a new reference in *at, but the returned should not be modified as it may be one of the canonical immutable objects or a reference to the input obj.
