need test for aogcm1d

[gaelforget]

Hi @udistr

I did some repackaging / streamlining of AOGCM1D.jl which is now part of the main module and thus available via using AirSeaFluxes as follows:

  outputs,parameters=AOGCM1D()

  p = dirname(pathof(AirSeaFluxes))
  include(joinpath(p,"recipes_plots.jl"))
  p1,p2,p3=plot_final(outputs,parameters)
  display(p3)

(see the dev docs https://gaelforget.github.io/AirSeaFluxes.jl/dev/)

I did this probably too quickly -- could you please rerun & verify that results are like you expected?

Once confirmed then it would be great to add a short test case -- e.g. with ndays to e.g. 2 or 3. What do you think?
