      Description

      The current updateRefCentroids and updateSourceCoords functions are pure Python and compute one position at a time. SkyWcs performs much better if it can convert a batch of values at once.

      I could rewrite the Python code to extract all the positions, convert them, then loop through the catalog again. But I worry this will be needlessly slow (the looping is already slow, and this will only make it worse), so I propose to rewrite the functions in C++ instead.
