Add logic to wcscorr.update_wcscorr that allows it to reformat an old WCSCORR table extension written out by previous versions of this code. The newly formatted table should contain all the previous table's information (as it gets created using init_wcscorr) and will conform to the latest table format (for now and for whatever that may end up being in the future). This will prevent the code from crashing when processing data updated with previous versions of 'updatewcs()' or 'tweakreg' from the drizzlepac package.
