PredictFractionalPeaks was using a new raytracer for every peak it created and therefore throwing away the caching information about the bounding boxs of detectors / panels causing a huge slow down. Resolved by exposing the findDetector(raytracer) overload to IPeaks and using single raytracer for all calls.
Work also include small refactor for const autos

If for some reason one of the radii is not defined SaveNexus crashes
because we access the value without checking it first. We should just
check that both radii are present, then write them out.
