Special case for 360 sphere

[shimwell]

@generein I had a quick look at issue #305 and wonder if we need a special case for the 360 degree sphere.

I've modified your original class to have a special route for the 360 degree rotated sphere

I've also added a few more tests to check volumes and number of faces on the result

I have not yet run this through the neutronics workflow, any chance you could test it for your use case
