Added borderValue parameter to rotate_bound(). #163

Hi!

This is such a useful package. I have been rotating images and wanted to have some control over the "extra space" revealed when the image is rotated. This is catered for by the borderValue parameter of the warpAffine() function.

This allows you to specify the "background colour" which is revealed when the image is rotated. By default this is black. Specifying borderValue=(255, 255, 255) will make this new portion of the image white.

Thanks, Andrew.
