Description

I would expect Int64Array type in all cases below :

>>> pa.array([4, None, 4, None], mask=np.array([False, True, False, True]))                                                                                  
<pyarrow.lib.Int64Array object at 0x91fad3a98> [4, null, 4,  null ]

>>> pa.array([4, None, 4, 'rer'], mask=np.array([False, True, False, True]))                                                                                    
<pyarrow.lib.Int64Array object at 0x9201f23b8> [4, null, 4,  null ]

>>> pa.array([4, None, 4, 3.], mask=np.array([False, True, False, True]))                                                                                        <pyarrow.lib.DoubleArray object at 0x91fab7638> [   4,   null,   4,   null ]
