Crash in erg_lepe_get_dist

When generating products from LEP-e 3dflux data, there is a crash in erg_lepe_get_dist:

    def test_lepe_theta(self):
        del_data('*')
        # Load LEP-e Lv.2 3-D flux data
        timespan('2017-04-05 21:45:00', 2.25, keyword='hours')
        pyspedas.erg.lepe( trange=[ '2017-04-05 21:45:00', '2017-04-05 23:59:59'], datatype='3dflux' )
        # Calculate and plot energy spectrum
        vars = erg_lep_part_products( 'erg_lepe_l2_3dflux_FEDU', outputs='theta', trange=[ '2017-04-05 21:45:00', '2017-04-05 23:59:59'] )

There's something different about the lepe CDFs -- the load routine calls cdf_to_tplot with notplot=True, because of some issue making tplot variables from the CDF variables. It's possible that something is still going wrong when the lepe load routine does its own conversion to tplot variables.
