Minor changes in IEEE P370 doc

[jhillairet]

• added some additional content in the introduction and some figures (@mhuser could you check it's OK?)
• use coherent terminology for labelling fixtures and DUT (following the one proposed in the standard)
• fix sphinx rendering of the lists

Great, the notebook is more clear and follow more closely the standard with this notation!

There is however a pitfall:

The svg are clear and neat and following the standard but the Matlab code ported to skrf, h is flipping FIX-2 in such a way DUT = FIX-1.inv ** FIX-DUT-FIX ** FIX-2.inv which is not correct according to the standard labelling.

I wonder if we should make FIX-2 compliant to the standard and svg so the equation would become FIX-1.inv ** FIX-DUT-FIX ** FIX-2.flipped().inv

I think it should, to match the standard labelling proposal.

@mhuser , shall I merge this one as you are working on the notebook too?

@jhillairet I think yes, I will be soon finishing the first proposal so hopefully, it will not last very long with the non-flipped numbering.
