Return a human-oriented string name of the dtype arg. This can be use by astropy methods that present type information about a data object.

The output is mostly equivalent to dtype.name which takes the form <type_name>[B] where <type_name> is like int or bool and [B] is an optional number of bits which gets included only for numeric types.

The output is shown below for bytes and str types, with <N> being the number of characters. This representation corresponds to the Python type that matches the dtype:

Numpy          S<N>      U<N>
Python      bytes<N>   str<N>
dtypestr, dtype, type

Input as an object that can be converted via numpy.dtype.
