Implement numpy argpartition

[ss32]

Is your feature request related to a problem? Please describe.
argpartition is a simple operation present in numpy that's missing from this library and I think it can be accomplished with existing funtions.

https://numpy.org/doc/stable/reference/generated/numpy.argpartition.html

Describe the solution you'd like
I think the hpp would look like

#pragma once

#include "NumCpp/Core/Types.hpp"
#include "NumCpp/NdArray.hpp"

namespace nc
{
    //============================================================================
    ///
    /// NumPy Reference: https://www.numpy.org/devdocs/reference/generated/numpy.argpartition.html
    ///
    /// @param inArray
    /// @param inKth: kth element
    /// @param inAxis (Optional, default NONE)
    /// @return NdArray
    ///
    template<typename dtype>
    NdArray<dtype> partition(const NdArray<dtype>& inArray, uint32 inKth, Axis inAxis = Axis::NONE)
    {
        NdArray<dtype> returnArray(inArray);
        returnArray.partition(inKth, inAxis);
        return returnArray.argsort(inAxis);
    }
}
