Migrate renaming into FEDS algorithm.
Right now, the API migration script has a fair amount of column renaming (@greg could you drop a link to the renaming code?). It would be better as part of the algorithm itself, because the algorithm could just write out the correct column names. @tmccabe mentioned that some column names may be appropriate for the API but not for the raw data. There also could be places where the data should just have a different column name.
@tmccabe will look at save_gpkgsfs
to see places where the column name should just be changed.
