Issue DM-2775: Improve SIP fitting
Dominique Boutigny says "the tan-sip fitter is very sensitive to bad matches. This is a weakness of the fitter and I think that it could (should) be rewritten in such a way to reject the outliers internally." This has resulted in iteration in the matching (DM-2755), which should be unnecessary (or at least minimised). Additionally, it seems the SIP fitter fits for x and y in subsequent iterations, which can confuse users. We should: 1. Make the SIP fitter fit for x and y concurrently. 2. Add rejection iterations in the SIP fitter. 3. Remove or minimise the iterations in the matching.
