Summary0015832: vtkExodusIIWriter: vtk int array converted to double
DescriptionWriting an Int array to an exodus file, the data is incorrectly stored as double in the file. An MWE
```
import numpy
import vtk
from vtk.util import numpy_support

points = [
    [0.0, 0.0, 0.0],
    [1.0, 0.0, 0.0],
    [1.0, 1.0, 0.0],
    [0.0, 1.0, 0.0]
    ]

mesh = vtk.vtkUnstructuredGrid()

# set points
vtk_points = vtk.vtkPoints()
# Not using a deep copy here results in a segfault.
vtk_array = vtk.util.numpy_support.numpy_to_vtk(points)
vtk_points.SetData(vtk_array)
mesh.SetPoints(vtk_points)

# TODO use numpy_support here, avoid the copying
c = numpy.array([
    3,
    0, 1, 2,
    3,
    0, 2, 3
    ], dtype=int)
a = vtk.util.numpy_support.numpy_to_vtkIdTypeArray(c)

cell_array = vtk.vtkCellArray()
cell_array.SetCells(2, a)
mesh.SetCells(vtk.VTK_TRIANGLE, cell_array)

# add int point data
X = numpy.array([7, 8, 3, -2], dtype=int)
array = vtk.util.numpy_support.numpy_to_vtk(X)
array.SetName('X')

pd = mesh.GetPointData()
pd.AddArray(array)

writer = vtk.vtkExodusIIWriter()
writer.SetFileName('test.e')
writer.SetInput(mesh)
writer.Write()
```

The array `X` is stored as `double` in `test.e`.
