run_msis() throwing a ValueError

[FasilGibdaw]

The following error while running run_msis()

ValueError: msis00py.msis00py.gtd7: failed to create array from the 9th argument ap -- 0-th dimension must be fixed to 7 but got 8

I think the get_apmsis.py script needs to be modified. Could making the output in this script of dimension of 7 by removing the interpolated ap index ap1 (index to avoid DWM discontinuities) still avoid the discontinuities? Removing it fixed the problem :).

Pull requests are very welcome. It's certainly possible that PR #149 introduced some error
