Improvements over make_psmap_plots #644

I think make_psmap_plots is doing too many things and the way it returns does not leave much freedom.
Describe the solution you'd like
The function right now is creating figures, saving them and then closing them returning anything.
If you just return the axis for each plot the user can make of it whatever needed and it will also be possible to show the plot in a jupyter notebook without loading the saved image which is not editable a posteriori
I propose to refactor it in three methods (1 per plot) and make each of them return the axis object
so the user can combine the plots as he/she pleases.
Let all kwargs be injected for whichever plot by setting defaults and let the user override them instead of hardcoding e.g. the colormap or the parameters or the maps or the binning.
gta.psmap with make_plots=True should just call all three with defaults and e.g. savefig=True
