Perform prediction refinement straight after indexing
This allows indexing to be attempted again (either a new method or with "retry") if the prediction refinement fails, increasing overall indexing rate. Side-effect: there are some hoops which would need to be jumped through to store the profile radius before refinement and hence enable scripts/plot-predict-refine to work. For now, we'll ignore this as it's clear that the prediction refinement is working.
