Be able to restrict reconstruction demand to affected regions

[spjuhel]

Is your feature request related to a problem? Please describe.
Reconstruction demand is directed toward all regions by default. It would be interesting to be able to restrict it to the affected region.
It would perhaps make more sense to distribute this demand in the model module rather than the event actually

Describe the solution you'd like
Handle the distribution of reconstruction demand in the model ? Or use a specific function ?

Describe alternatives you've considered
Implement new mechanism in the event module to distribute only to the affected region.

with something inspired by:

industrial_rebuilding_demand = np.zeros(shape=ev.z_shape)
mask = np.ix_(
            np.union1d(
                ev._rebuilding_industries_RoW_idx, ev._rebuilding_industries_idx
            ),
            ev._aff_industries_idx,
        )
mask = np.ix_(
          ev._rebuilding_industries_idx, ev._aff_industries_idx,
        )
tmp = np.zeros(ev.z_shape, dtype="float")

ev._rebuilding_sectors_shares[
                ev._rebuilding_industries_RoW_idx
            ] = 0
