suspected mistake in get_lennard_jones_potentials function

[DaniBodor]

in features.atomic_contact the get_lennard_jones_potentials function ends with

    # calculate potentials
    sigmas = 0.5 * (sigmas1 + sigmas2)
    epsilons = np.sqrt(sigmas1 * sigmas2)
    potentials = 4.0 * epsilons * ((sigmas / distances) ** 12 - (sigmas / distances) ** 6)

I suspect it should be (3rd line different)

    # calculate potentials
    sigmas = 0.5 * (sigmas1 + sigmas2)
    epsilons = np.sqrt(epsilons1 *epsilons2)
    potentials = 4.0 * epsilons * ((sigmas / distances) ** 12 - (sigmas / distances) ** 6)

can you confirm, please @cbaakman

Yes, sorry about the mistake!
