POI does not support to compute the conflict

[guilhermebodin]

ERROR: LoadError: ArgumentError: The optimizer ParametricOptInterface.Optimizer{Float64, Xpress.Optimizer} does not support `compute_conflict!`
Stacktrace:
 [1] compute_conflict!(optimizer::ParametricOptInterface.Optimizer{Float64, Xpress.Optimizer})
   @ MathOptInterface C:\Users\guilhermebodin\.julia\packages\MathOptInterface\mz9FK\src\MathOptInterface.jl:108
 [2] compute_conflict!(model::Model)

Probably a simple new dispatch would do the trick
