CSPAD pixel coordinate arrays

Here we reproduce the test method
example_of_image_built_from_pix_coordinate_array_shaped_as_data()
from the module Examples.py.
This example shows how to get the CSPAD pixel coordinate arrays. In addition, it uses the getTestImageShapedAsData(ds1ev) (slow) method to produce image from the pixel coordinate arrays and data and plots this image.
