"""
Simple method to convert the DEIMOS .sav files, which contain the
optical model maps, to .fits files. The new file has the
same name with a .fits extension.
ToDO: This is specific for keck_deimos `static_calib` data, since the path
is explicitly mentioned. If needed, this method could be generalized.
TODO: move it to `pypeit.io`.
Args:
savfile (str): full path to the .sav file
