Updating the ANL-AFCI-177 tutorial wire wrap helix diameter so that the pin pitch aligns with the reference. This
changed the helix diameter from 0.84825 cm to 0.8888 cm and fixes the issue identified in #311.

This is updated to 0.777 cm because the reflector slug OD is 0.6962 cm and not the same as the clad OD dimensions for the fuel. This leads to a smaller pitch.

I wonder where that reflector pin OD came from. Maybe later we should just make that equal to the fuel pin OD just to make it less strange.
