 mfsa_idf::get_geometry
        Return the geometry factors for an MFSA channel or set of
        channels.

 Usage:
        gf = idfref -> get_geometry([channels], {/lefs|/lems})

 Argument:
        channels        int     Channel or range of channels for which
                                GF is needed (if not given all 32 are
                                returned)

 Keywords:
        lefs    If set, then return the geometry factors for the LEFS
                heads
        lems    If set, then return the geometry factors for the LEMS
                heads

 Notes:
        Exactly one of the lems & lefs keys must be given.
