- HSTWCS class was modified to

  - not keep the headers as attributes
  - accept an adittional paramter fobj, consistent with SIP and WCS classes.
  - The restore method was renamed to get_archive and moved to utils
- corrections classes:
  - updateWCS were turned into classmethods
  - diff_abgles was moved to utils
- restoreWCS() was moved to utils
