 mfsa_idf::get_energy
        Return the energy for an MFSA channel or set of
        channels.

 Usage:
        gf = idfref -> get_energy([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 energy for the LEFS
                heads
        lems    If set, then return the energy for the LEMS
                heads
        centre  If set then return the nominal band-centre energy
                (otherwise the range is returned).
        all     If set and a channel list is given, then return all
                the intermediate values as well (otherwise only the
                limits are returned).
        species Either a species name or a species index for which the
                energies are needed. (If not given, protons are
                assumed).
        kev     If set, then return energy in keV

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