Custom read zero outside image

[haesleinhuepf]

Hey @grahamross123 ,

I eventually managed to look into #296 . Big thanks for working on this!

In this PR to your branch I add a custom read-function based on the original in the preamble. It returns 0 if the coordinates are outside the image.

I'm also adding some tests demonstrating that it now works like in skimage also on image borders.

I created an issue because the read-zero-outside thingy should be supported by the preamble, but is commented out. See #302

Let me know what you think! And thanks again!

Best,
Robert
