Fix reference frame saved as ICRS instead of FK5

Simon Conseil requested to merge coords into master

MUSE files and several HST files have EQUINOX=2000.0 only in the primary header, which MPDAF didn't use until now. So, headers produced by wcs.to_header and saved to files were using RADESYS='ICRS' instead of 'FK5'.

This branch adds the optional frame and equinox parameters for WCS, and parse the primary header to find EQUINOX or RADESYS and create a WCS in the correct reference frame.
