Make sure the leaf area from the 3D reconstruction matches the one computed by XPalm

[VEZY]

The leaf area is a result of the reconstruction in VPalm, which depends on the rachis length, which helps computing the number of leaflets, then the length of the reference lealfet, then the length of all leaflets, then their maximum width, and finally we build a mesh from that. So the leaf area is the sum of all leaflets area. But XPalm also has its own computation of the leaf area based on its biomass:

function PlantSimEngine.run!(m::LeafAreaModel, models, status, meteo, constants, extra=nothing)
    status.leaf_area = status.biomass * m.leaflets_biomass_contribution / m.lma_min
end

Note that the amount of biomass produced by palm trees depends on the demand, which is determined by the potential leaf area. This potential area is in turn influenced by the age of the palm at leaf initiation.

We need to verify that the 3D reconstruction's leaf area matches the area computed by XPalm.
