JuMP v1.0

[blegat]

Could this package be updated to JuMP v1.0? It's already working with JuMP v0.23 so it might be quite easy

[vOptSolver]

The update is scheduled for the coming weeks. It will come with new solving methods (a p-objectives epsilon-constraint method implementing the Kirlik-Sayin algorithm, and we are also working on a 2-objective simplex method based on the solver HiGHS).
