A conglomerate trap as class?

[RemDelaporteMathurin]

Something like

trap_1 = F.Trap(1, 1, 1, 1, density=1, materials=tungsten)
trap_2 = F.Trap(2, 2, 2, 2, density=2, materials=copper)


trap_conglo = F.Multitrap([trap_1, trap_2])

This would be the equivalent of:

trap_conglo = F.Trap([1, 2], [1, 2], [1, 2], [1, 2], density=[1, 2], materials=[tungsten, copper])

But more readable

This would simplify the parameters logic inside FESTIM.Trap
